# What You'll Need:
→ Base
01 - 1 large egg, at room temperature
02 - 1 tablespoon Dijon mustard
03 - 1 tablespoon white wine vinegar or lemon juice
→ Oil
04 - 1 cup neutral oil such as 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 - Add the egg, Dijon mustard, white wine vinegar or lemon juice, salt, and black pepper (if using) into a tall, narrow blending container.
02 - Pour the neutral oil on top, ensuring it forms a separate layer above the base ingredients.
03 - Insert the immersion blender until it reaches the bottom of the container.
04 - Switch on the blender and keep it at the bottom for about 10 seconds, allowing the mixture to begin emulsifying and turning creamy.
05 - Gradually raise and lower the blender to incorporate all the oil thoroughly, blending until the mixture is thick and smooth, approximately 30 seconds.
06 - Taste and adjust salt, pepper, or acidity as desired.
07 - Spoon into a clean jar, seal tightly, and refrigerate. Consume within 1 week.
