Basic Soy Mayonnaise

1 c soy milk powder (we prefer unsweetened, and suggest Soy Supreme, regular brand, which contains the whole soybean, including its fiber)

2 c water

1 tsp salt

¼ tsp or more to taste, garlic powder

1½ tsp onion powder

juice of 1 fresh lemon

¼ c oil, we suggest extra-virgin olive

Blend smooth all ingredients except the oil and lemon juice. Continue blending and slowly pour the oil in. Stir or blend in lemon juice last. Chill.
