Ingredients

1 ¼ cup light olive oil
1 egg *room temperature
2-4 tbsp fresh lemon juice *start with 2 tbsp and add more lemon juice to taste.
½ tsp sea salt
½ tsp dried mustard

Instructions

First, place ¼ cup of the olive oil in the food processor or blender and set the rest aside. Add the egg, mustard powder, and fine sea salt, and start to blend on low.
Then, very slowly drizzle in the rest of the olive oil. Make sure that the stream of oil is really thin as you drizzle it in and that you pour very slowly. This is important for thick and creamy mayo. Once all of the oil has been added, blend in 2 tablespoons of lemon juice.
Next, turn off the appliance and taste for seasoning. Add more lemon juice or salt to taste.
