When you are cooking and baking and the recipe calls for milk, use whole milk. You will be baking more goodness into whatever it is you are taking the time to make. You do not need to be afraid of it. Did you know that when you buy 2% if means you are getting 2% milk fat, and whole milk gives you about 4%? The difference is not that great, but it will make a big difference in your finished recipe. This kind of "fat" equals goodness in baking. Mother Rabbit would say never cook with skim milk. It is not really milk in her opinion.
I had the pleasure to buying raw whole milk straight off of a family farm today. This brings back memories from my childhood that I am enjoying.
