Cut margarine into pieces. Put into food processor and turn it on. Slowly add oil through chute. Slowly add water. Add pinch of salt if desired. Mix until smooth.
Notes
I use sunflower oil, nice and light.
This is a shortening substitute and works fine for many things. It cuts down on the amount of hydrogenated fats from straight margarine.
Substitutions
Butter and Margarine: Butter is a dairy product made from cow’s milk. Margarine typically contains milk or soy, but there are milk-free and soy-free versions available.
Milk and Soy Substitutions: Alternative dairy-free milk beverages and products will work in most recipes. Find out more about milk substitutions and soy substitutions.
