Homemade Mayo

1 egg yolk
2 T. lemon juice or vinegar
1 tsp. dry mustard
1 tsp. sugar
Dash of ground red pepper
1 c. vegetable oil or olive oil

Beat egg yolk, lemon juice, mustard, sugar, salt and red pepper with a hand mixer on medium speed until lemon colored. Increase speed to high, beat in oil, 1 drop at a time: increasing rate of addition as mixture thickens - this takes a while, be patient. Pour into jar and refrigerate.
Makes 1 cup. Recipe doubles well.

NOTE: if by chance the mixture separates, you can rescue it by starting over with fresh egg yolks and oil, add the separated mixture gradually when it's about half made.
