# What You'll Need:
→ Base
01 - 1 large egg, room temperature
02 - 1 tablespoon Dijon mustard
03 - 1 tablespoon white wine vinegar or lemon juice
→ Oil
04 - 1 cup neutral oil (sunflower, canola, or light olive oil)
→ Seasoning
05 - 1/2 teaspoon fine sea salt
06 - 1/4 teaspoon freshly ground black pepper (optional)
# Cooking Steps:
01 - Combine the egg, Dijon mustard, vinegar or lemon juice, sea salt, and black pepper (if desired) in a tall, narrow container compatible with an immersion blender.
02 - Pour the neutral oil on top of the ingredients in the container.
03 - Insert the immersion blender fully to the container's base. Switch it on and blend for approximately 10 seconds without moving, allowing the mixture to start emulsifying.
04 - Gradually raise and lower the blender to thoroughly incorporate the oil. Continue blending until the consistency is thick and creamy, about 30 seconds.
05 - Taste and adjust the seasoning to preference. Transfer to a clean jar, cover tightly, and refrigerate.
06 - Store refrigerated and use within 1 week for optimal freshness.
