(Makes 16 Tablespoons)
1 raw egg yolk (pasteurized in the shell egg if available)
2 teaspoons champagne vinegar or white wine vinegar
1/4 teaspoon salt
1/2 lemon, juice only (about 1 tablespoon)
1/4 teaspoon dry mustard
dash cayenne pepper
3/4 to 1 cup olive oil (needs to be taste free so a light non-virgin variety or use a blend with canola oil)

1. Crack egg and put yolk only into the blender
2. Add the vinegar and salt and blend on low speed.
3. With the motor running, add all the remaining ingredients, except the oil.
4. With the motor still running, add the oil in a slow, steady stream until it makes mayonnaise of the consistency you desire. Be careful not to add the oil too fast or add too much oil or you may break the emulsion and the mayonnaise will separate and clump.*
5. Store in the refrigerator in a clean jar (good use for store-bought mayonnaise) or a container with a tight-fitting lid for up to a week.

I make this with my stick blender. Takes a minute and it tastes great.
