PREPARATION SUGGESTIONS
FINISH VEGETABLES
Weigh the butter added to cooked vegetables and include the vegetables and other ingredients in the meal total.
MAKE A FLAVORED BUTTER
Mix a measured amount with herbs or seasoning. Divide by the finished mixture weight when calculating a serving.
CHOOSE A BAKING FORMULA
Use a recipe written for butter. Substituting oil changes the water and fat proportions, so a one-for-one swap is not established here.
