# 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, 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
# Method:
01 - Place the egg, Dijon mustard, vinegar or lemon juice, sea salt, and black pepper in a tall, narrow blending container suitable for an immersion blender.
02 - Pour the neutral oil directly on top of the mixture.
03 - Insert the immersion blender fully to the bottom of the container without blending yet.
04 - Activate the blender and keep it at the bottom for approximately 10 seconds, allowing the mixture to begin emulsifying and become creamy.
05 - Slowly raise and lower the blender through the mixture to fully blend all oil. Continue blending until the mayonnaise thickens and achieves a smooth texture, about 30 seconds total.
06 - Taste the mayonnaise and adjust salt, pepper, or acidity as needed.
07 - Transfer the mayonnaise to a clean jar, seal tightly, and refrigerate. Consume within one week for optimal freshness.
