I love olive oil mayo! I ran out in the middle of a yucky rainy day and decided to make my own, instead of going out in the damp. I looked through a few different cookbooks and took the best of each to come up with this recipe.
1 whole egg, 1/2 tsp. salt, 1/2 tsp. sugar, dash of Old Bay Seasoning,
2 TBSP vinegar or lemon juice, 1/2 cup vegetable oil and 1/2 cup olive oil in one measuring cup.
In blender add egg, salt, sugar, seasoning, vinegar and 2 TBSP of the oil.
Pulse 5 or 6 times to blend smooth.
On the "blend" speed, SLOWLY DRIZZLE oil until thick and creamy.
You may have to stop and scrape, once, when it gets thick,
so it will blend the rest of the oil.
Spoon into a jar and refrigerate immediately. It makes a little more than a cup. I don't know how long it will last, because we go through it in a week.
I have made this every Saturday afternoon, lately.
