Ingredients

1 large egg, room temperature 

1/2 cup extra-virgin olive oil 

1 teaspoon coarse salt 

1 cup safflower oil 

1 tablespoon fresh lemon juice 

Preparation

Combine egg, 1 teaspoon olive oil, and the salt in a blender, and blend at lowest speed.

With blender still running, add remaining olive oil and the safflower oil in a slow, steady stream, and blend until incorporated (if you prefer a thicker mayonnaise, blend 10 seconds more at a higher speed).

Transfer mayonnaise to a bowl, and stir in lemon juice. Serve immediately or refrigerate up to 2 days.
