Mayonnaise is a staple condiment in many kitchens, known for its creamy texture and versatility. But when infused with truffle essence, it transforms into something truly luxurious. Truffle mayonnaise adds an unmistakable depth of flavor to burgers, sandwiches, fries, and even salad dressings. Unlike commercially available truffle mayo, which often contains artificial flavors or excessive amounts of truffle oil, this homemade version lets you control the balance, ensuring a refined, restaurant-quality taste.

Because truffle essence is highly concentrated, we start with just 1/16 teaspoon (0.3 mL) per 1 cup (240 mL) of mayonnaise. This ensures a subtle, well-balanced infusion without overwhelming the dish. If a stronger truffle aroma is desired, you can add more to taste.

Truffle Essence Mayonnaise Recipe

Ingredients

• 1 cup (240 mL) neutral oil (such as grapeseed, avocado, or light olive oil)
• 1 large egg yolk (room temperature)
• 1 teaspoon (5 mL) Dijon mustard
• 1 teaspoon (5 mL) fresh lemon juice
• ½ teaspoon (2.5 mL) white wine vinegar
• ½ teaspoon (2.5 mL) fine sea salt
• 1/16 teaspoon (0.3 mL) truffle essence, or more to taste

Equipment Needed

• Mixing bowl (if whisking by hand) or immersion blender
• Whisk or blender
• Measuring spoons
• Small airtight jar (for storage)

Step-by-Step Instructions

Step 1: Prepare Your Ingredients

• Bring the egg yolk to room temperature before starting, as this helps emulsify the mayonnaise more easily.
• Choose a neutral oil to ensure that the truffle essence remains the dominant flavor. Avoid strong-flavored oils like extra virgin olive oil, which can compete with the truffle aroma.

Step 2: Begin the Emulsion

• In a mixing bowl, whisk together the egg yolk, Dijon mustard, lemon juice, vinegar, and salt. This combination forms the base of the emulsion, giving the mayonnaise its thick texture and slight tanginess.

Step 3: Slowly Incorporate the Oil

• While continuously whisking (or using an immersion blender), slowly drizzle in the oil in a thin, steady stream.
• At first, add just a few drops at a time, ensuring the mixture thickens before adding more. This process is crucial for proper emulsification.
• Continue whisking and gradually increase the amount of oil being added until the mixture turns into a thick, creamy mayonnaise.

Step 4: Add the Truffle Essence

• Carefully measure 1/16 teaspoon (0.3 mL) of truffle essence and stir it into the mayonnaise.
• Taste the mayo—if you desire a stronger truffle presence, add a drop or two more, mixing thoroughly each time.

Step 5: Adjust Seasoning and Store

• Once the truffle essence is well incorporated, taste the mayonnaise and adjust the seasoning. Add a bit more salt, vinegar, or lemon juice if needed.
• Transfer the truffle mayonnaise to an airtight container or jar and refrigerate for at least 30 minutes before using. This allows the flavors to meld together, resulting in a more cohesive truffle aroma.

Ways to Use Truffle Mayonnaise

Truffle mayonnaise is a versatile condiment that can elevate everyday dishes. Here are some of the best ways to incorporate it into your cooking:

1. Spread on Burgers & Sandwiches

• Slather truffle mayo on a juicy cheeseburger or a gourmet grilled chicken sandwich for a touch of decadence.
• Pair it with roast beef, turkey, or BLTs to bring a sophisticated flavor to your favorite sandwiches.

2. Dip for Fries & Roasted Potatoes

• Serve as a dipping sauce for crispy French fries, sweet potato fries, or roasted potato wedges.
• Sprinkle a little Parmesan cheese and fresh herbs on the fries for an extra gourmet touch.

3. Toss with Vegetables & Salads

• Mix with shredded cabbage and carrots for an elevated truffle-infused coleslaw.
• Thin it out with a little extra vinegar and lemon juice to make a luxurious truffle salad dressing.

4. Use in Deviled Eggs

• Replace regular mayo with truffle mayo in deviled eggs for an upscale twist on a classic appetizer.

5. Drizzle on Roasted Meats & Seafood

• Pair with grilled steak, roasted chicken, or pan-seared salmon as a flavorful finishing sauce.

Storage & Shelf Life

• Refrigeration: Store truffle mayo in an airtight container in the refrigerator for up to 5 days.
• Avoid Freezing: Mayo does not freeze well due to its emulsified nature, so it’s best to make it fresh as needed.

Variations & Customizations

Want to tweak the truffle mayonnaise to fit your personal taste? Here are some easy modifications:

1. Garlic Truffle Mayo

• Add ½ teaspoon (2.5 mL) minced fresh garlic or ¼ teaspoon (1.25 mL) garlic powder for an aromatic boost.

2. Spicy Truffle Mayo

• Mix in ½ teaspoon (2.5 mL) Sriracha or a pinch of cayenne pepper for a spicy kick.

3. Lemon Herb Truffle Mayo

• Stir in 1 teaspoon (5 mL) finely chopped parsley, thyme, or chives along with an extra squeeze of lemon juice for a bright, herbaceous take.

4. Vegan Truffle Mayo

• Replace the egg yolk with aquafaba (chickpea water) and use vegan mayonnaise as a base.
