A bright and creamy homemade condiment that transforms simple meals. Fresh herbs and lemon zest meld into a rich base, perfect for sandwiches, dips, and sauces. It’s a quick flavor booster that improves after chilling.

Ingredients

Scale
  • 1 large egg yolk, at room temperature
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon finely grated lemon zest
  • 1 teaspoon Dijon mustard
  • 1/2 teaspoon fine sea salt
  • 1 cup neutral oil, such as avocado or light olive oil
  • 1/4 cup packed fresh soft herbs, such as parsley, dill, and chives
  • 1 small clove garlic, minced (optional)

Instructions

  1. In a medium bowl, whisk together the egg yolk, lemon juice, Dijon mustard, and salt until pale and slightly thickened, about 1 minute.
  2. While whisking constantly, begin adding the oil drop by drop for the first 1/4 cup to build a stable emulsion.
  3. Once the mixture has thickened, continue whisking and add the remaining oil in a thin, steady stream until fully incorporated and creamy.
  4. Gently fold in the fresh herbs, lemon zest, and minced garlic (if using) until evenly distributed.
  5. Taste and adjust seasoning with more salt or lemon juice if desired. For a thinner consistency, whisk in a teaspoon of warm water.

Notes

For a shortcut, use 1 cup store-bought mayo as a base and whisk in the lemon zest, juice, and herbs. If the mayonnaise breaks, whisk a fresh egg yolk in a clean bowl and slowly incorporate the broken mixture drop by drop to re-emulsify. Store in an airtight container in the refrigerator for up to 5 days.
