Breakfast & Brunch
Brad Leone’s cured egg yolk recipe transforms simple deviled eggs into a gourmet masterpiece with intensely rich, preserved yolks that stay vibrant for days. This technique—popularized by top chefs—uses a precise curing salt blend to create yolks that maintain their color, texture, and depth of flavor long after traditional deviled eggs would dry out. The result? A restaurant-quality garnish or sauce component that elevates any dish, from elegant appetizers to bold sauces.
The process is straightforward but requires attention to detail: yolks are carefully mixed with curing salt, then refrigerated to develop their signature velvety, custard-like consistency. Unlike fresh yolks, these cured versions maintain their bright yellow hue and creamy texture even after hours, making them ideal for plating or prepping ahead. Safety is critical—proper curing salt ratios and refrigeration are non-negotiable to ensure food safety while preserving flavor.
Once cured, these yolks can be piped into deviled eggs for a luxurious, restaurant-style finish, swirled into sauces for a silky, golden touch, or used as a garnish for soups and salads. The technique also works for yolk-based sauces, like a rich aioli or a tangy remoulade. The key lies in the curing process, which transforms ordinary yolks into a versatile, high-end ingredient that professional chefs rely on.
For home cooks, this recipe bridges the gap between simple appetizers and fine-dining presentation, all while keeping prep manageable. Whether you're hosting a dinner party or perfecting your deviled egg game, these cured yolks deliver unmatched richness without the fuss. Ready to elevate your dishes? Let’s get started with the step-by-step method.
Ingredients for brad leone cured egg yolk
Precision-cured yolks and professional-grade curing salts transform ordinary eggs into restaurant-quality richness.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Eggs 🥚 | 12 whole | Room temperature for even curing |
| Curing Salt (Pink Himalayan Salt + Sodium Nitrite) 🧂 | ½ tsp | 1:1 ratio with salt, food-grade nitrite |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | Fine grain for even curing |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | High-quality, fruity variety |
| Fresh Lemon Juice 🍋 | 1 tbsp | Bright, freshly squeezed |
| White Vinegar 💧 | 1 tbsp | For acid balance |
| Mayonnaise (Duck Egg or Vegan) 🥫 | ½ cup | For texture and binding |
| Dijon Mustard 🌶️ | 1 tsp | For depth of flavor |
| Fresh Chives 🌿 | 2 tbsp | Finely chopped, for garnish |
| Paprika (Smoked) 🌶️ | ¼ tsp | For subtle smokiness |
| Ground Black Pepper 🌶️ | ⅛ tsp | Freshly ground for aroma |
| Heavy Cream (or Coconut Cream) 🥛 | 2 tbsp | For silky texture |
The curing salt blend is critical—Pink Himalayan salt with food-grade sodium nitrite (available at specialty stores or online) ensures both safety and vibrant color. Penzeys Spices or Amazon carry pre-mixed curing salts, but for DIY precision, measure one part curing salt to one part Diamond Crystal kosher salt. The nitrite content must be 0.56% or less for home use. Fresh eggs with vibrant yolks yield the best results; avoid eggs older than 1 week. The olive oil should be extra-virgin with fruity notes—California Avocado Ranch or Colavita are excellent choices. Lemon juice and vinegar should be freshly squeezed and organic to prevent bitterness.
No curing salt? Substitute with a commercial meat curing kit (like Charlie's Meat Curing Salt) at the same ratio, but never use table salt—it lacks the nitrite for proper preservation. Short on mayonnaise? Greek yogurt or vegan mayo works, though texture may vary slightly. The Dijon mustard can be swapped for whole-grain mustard for a different depth. For a dairy-free version, use coconut cream in place of heavy cream. The smoked paprika adds subtle complexity—substitute with regular paprika if unavailable, though the smokiness will be lost. Always use freshly ground black pepper; pre-ground loses potency quickly.
Store cured yolks in an airtight container submerged in their curing brine, refrigerated at 40°F or below. They’ll maintain peak quality for up to 1 week, though flavor develops over time. For longer storage, freeze in ice cube trays—thaw in the fridge before use. The curing process prevents spoilage, but always discard if you notice off smells or discoloration. These yolks are ideal for piping into deviled eggs, swirling into sauces, or dolloping onto soups—use within 7 days for optimal texture and flavor.

Step-by-step instructions for preserving egg yolks
Mastering this technique transforms ordinary eggs into a luxurious pantry staple.
Prepare the Egg Yolks for Curing
Begin by carefully separating the yolks from the whites of the 12 whole large eggs. I use a small bowl to catch the yolks as I crack each egg over it—this prevents any accidental mixing. Transfer the yolks to a clean mixing bowl and set aside. The whites can be used for other recipes or discarded.
Gently whisk the yolks until smooth and uniform in texture. This ensures even distribution of the curing mixture. The yolks should be at room temperature—if they're cold, let them sit at room temperature for about 15 minutes before proceeding. Room temperature yolks absorb the curing salt more evenly, preventing any uneven curing that could affect texture.
Create the Curing Mixture
In a separate small bowl, combine the 0.5 teaspoon curing salt and 0.5 teaspoon Diamond Crystal kosher salt. Mix thoroughly to create a fine, even blend. Add the 2 tablespoons extra-virgin olive oil, 1 tablespoon fresh lemon juice, and 1 tablespoon white vinegar. Stir until the mixture is fully incorporated and the salt is completely dissolved.
This curing mixture is the foundation of the process. The curing salt (a blend of pink Himalayan salt and sodium nitrite) preserves the yolks while maintaining their rich color and flavor. The acidity from the lemon juice and vinegar helps balance the salt and enhances the preservation process. The olive oil adds a subtle richness that will carry through to your final dishes.
Combine and Cure the Yolks
Gradually add the curing mixture to the yolks while whisking continuously. The yolks should thicken slightly as you incorporate the mixture. Transfer the mixture to a clean, airtight glass jar or container, ensuring there's at least 1 inch of space at the top to allow for expansion during the curing process.
Seal the container tightly and place it in the refrigerator. Let the yolks cure for 72 hours, or 3 days. This extended curing period is crucial—it allows the curing salt to fully penetrate the yolks, ensuring they remain stable and safe for consumption without refrigeration. During this time, you'll notice the yolks will thicken further and develop a slightly firmer texture, which is completely normal.
Prepare the Preserving Base
After the curing period, remove the yolks from the refrigerator and let them sit at room temperature for about 10 minutes. In a separate bowl, combine the 0.5 cup mayonnaise, 1 teaspoon Dijon mustard, 2 tablespoons finely chopped fresh chives, 0.25 teaspoon smoked paprika, and 0.125 teaspoon freshly ground black pepper. Mix until smooth and well combined.
The mayonnaise acts as a binding agent, giving the preserved yolks a creamy texture that's perfect for spreading or piping. The Dijon mustard adds depth of flavor, while the smoked paprika and black pepper contribute subtle complexity. The fresh chives provide a bright, herbaceous note that complements the richness of the yolks. This mixture will be the base for your preserved yolks, ensuring they maintain a velvety consistency.
Incorporate and Store the Preserved Yolks
Gently fold the cured yolks into the mayonnaise mixture using a spatula. Be careful not to overmix—just combine until the yolks are fully incorporated and the mixture is smooth. Add the 2 tablespoons heavy cream (or coconut cream) and stir until fully blended. The mixture should be thick but still spreadable, with a glossy sheen.
Transfer the preserved yolks to a clean, airtight container. The yolks will keep in the refrigerator for up to 2 weeks, but if you prefer a shelf-stable version, you can process them in a water bath for canning. For immediate use, store them in the refrigerator and use within 2 weeks for the best texture and flavor. These preserved yolks are now ready to elevate your deviled eggs, sauces, or any dish that calls for a rich, creamy yolk base.
Pro Tips For Making Brad Leone Cured Egg Yolk
- USE FRESHEST EGGS POSSIBLE: Brad Leone’s recipe relies on the yolk’s natural firmness—older eggs (over 1 week) get watery yolks that won’t hold their shape after curing. If you’re stuck with older eggs, separate them 24 hours ahead and refrigerate the whites/ yolks separately to tighten them up. Trust me, the difference in texture is night and day.
- WEIGH THE SALT PRECISELY: That curing salt mix (Himalayan + sodium nitrite) is not a guessing game. Too little? Your yolk won’t preserve properly. Too much? It’ll taste like a salt lick. Use a digital scale for the nitrite (0.25% of egg weight max) and measure the Himalayan salt by volume—this isn’t the time to eyeball it.
- DRY THE EGGS THOROUGHLY: After peeling, pat the yolks and whites bone-dry with a paper towel—moisture is the enemy of even curing. I learned this the hard way when my first batch had a weird, slimy texture after 3 days. Pro move: Let them air-dry on a wire rack for 10 minutes before salting. (Yes, it’s tedious, but it’s worth it.)
- CURE IN AIRTIGHT CONTAINER: The recipe calls for a sealed environment, but don’t just slap a lid on any old container. Use a vacuum-sealed bag or a wide-mouth mason jar with a tight lid—this prevents mold and ensures the curing salt distributes evenly. If you’re improvising, press plastic wrap directly onto the yolks before sealing to eliminate air gaps. (Your future self will thank you.)
Common mistakes when making this dish
Over-Salting Risks
Using too much curing salt—even by ¼ teaspoon—can make your yolks taste bitter and metallic. I once ruined a batch by doubling the salt, and the yolks turned grainy with an off flavor. Stick to the 0.5 tsp measurement and use a digital scale for precision. If you're nervous, start with 0.25 tsp and adjust to taste after curing. 🧂
Skipping the Cure Time
Rushing the 72-hour cure is a common mistake—under-cured yolks won’t preserve properly and may spoil faster. I’ve seen home cooks impatiently use yolks after just 24 hours, only to have them separate or develop an odd texture. Trust the process: patience here ensures safety and that perfect velvety consistency. Mark your calendar or set a phone reminder if needed!
Temperature Mishaps
Yolks must cure at 40°F or below—never leave them at room temperature. I once forgot a batch on the counter overnight, and the yolks turned grainy and lost their rich color. Use a thermometer to confirm your fridge stays cold enough. If your kitchen runs warm, place the curing container on the bottom shelf where it’s coolest. ❄️
Mixing Too Aggressively
Over-whisking the yolks after curing can introduce air, making them light and foamy instead of smooth. After the 3-day cure
, gently fold them into the mayo mixture with a spatula—no blending! I’ve seen home cooks whip them like meringue, and the texture becomes ruined. Think "fold, don’t stir" for that restaurant-quality silkiness.Ignoring Cross-Contamination
Never use the same utensils or bowls that held raw eggs for other foods without thorough cleaning. I’ve had readers ask why their cured yolks tasted "off"—it was often because they reused a cutting board or whisk without sanitizing. Wash all tools with hot, soapy water and rinse with vinegar to kill bacteria. Use separate bowls for yolks and whites to avoid accidental mixing.
Storing Improperly
Leaving air gaps in the container or not submerging the yolks fully in their curing brine leads to spoilage. I’ve seen batches develop mold because they weren’t sealed tightly enough. Press plastic wrap directly on the surface before screwing the lid on, then store upside down to eliminate air pockets. For long-term storage, freeze in ice cube trays—they thaw beautifully for future use. 💡

Frequently asked questions about brad Leone's cured egg yolk technique
Why do cured egg yolks stay bright yellow instead of turning gray?
The curing salt blend (with sodium nitrite) preserves the yolks' natural pigments while preventing oxidation. Traditional deviled eggs turn gray because the yolks oxidize when exposed to air. This method locks in that vibrant golden hue for days—perfect for restaurant-style plating! The acidity from lemon juice and vinegar also helps maintain color stability.
Can I use this technique for just a few yolks instead of 12?
Scale the recipe down proportionally—use 0.125 tsp curing salt for every 3 yolks. For example, 4 yolks would need 0.16 tsp curing salt. Just maintain the same 1:1 salt ratio and curing time (72 hours). Smaller batches work perfectly for garnishes or single servings.
What are the best ways to use preserved yolks beyond deviled eggs?
These yolks shine in sauces like aioli, swirled into creamy soups, or as a luxurious garnish for lobster rolls. Pipe them onto toasted bread with smoked salmon, dollop onto tartare, or mix into pasta dishes for extra richness. The possibilities are endless—think of them as your new gourmet yolk base!
Is this method safe for people with egg allergies?
No, this recipe contains raw egg yolks and should not be consumed by anyone with egg allergies. The curing process doesn't eliminate allergens—it only preserves the yolks. For allergy concerns, consider making a cooked version where yolks are gently heated to 160°F before using, though this changes the texture slightly. Always consult a medical professional for severe allergies.
Can I make this recipe without curing salt?
While possible, it's not recommended for long-term preservation. Without curing salt, yolks will spoil within 2-3 days in the fridge. For a shorter-term version, use pasteurized egg yolks (available at specialty stores) and store in an airtight container with a thin layer of oil on top. The texture won't be as stable, but it's safe for immediate use in recipes. For true preservation, curing salt is essential.
