Greebo’s Cooked Mayonnaise

2 egg yolks
2 tbsp. vinegar or lemon juice
2 tbsp. water
Sweetener equivalent to  a tsp. sugar
1 tsp. mustard  ( dry or wet)
Dash pepper

Plus, whatever else takes your fancy, e.g. a dash of curry powder or garlic. I cup oil ( I use olive, but whatever, there is lots of debate about oils, I suppose canola might be ok, its cheaper)

In a small saucepan, stir together egg yolks, vinegar, sweetener, mustard, salt and pepper until blended. Cook over a very low heat, stirring constantly, until mixture bubbles in 1 or 2 places. Remove from heat. Stand to cool slightly (about 4 minutes), then pour into blender. Blend at high speed while slowly pouring in oil in a very thin stream. (need to be patient with at least the first 1/4 cup so as the oil will emulsify). Occasionally stop the blender, and scrape down sides if necessary. put in a glass jar in fridge.
