Here is a simple, yet delicious, recipe from allrecipes. The key is to warm the milk and butter before adding it to the potatoes.
2 pounds baking potatoes, peeled and quartered
2 tablespoons butter
1 cup (soy) milk
salt and pepper to taste
Bring a pot of water to a boil. Add potatoes and cook until tender, but still firm; about 15 minutes. Drain.
Meanwhile, in a small saucepan heat butter and milk until butter has melted.
Using a potato masher, mash the potatoes and slowly add the milk-butter mixture, until it reaches desired consistency.
Season with salt and pepper as desired.
If I have labeled a recipe as GlutenFree
or Dairy Free but it appears to have those ingredients in it... that
means the recipe is still delicious with substitutes/replacements. Ex:
soy milk, lactose-free cheese, Bragg's liquid aminos (for soy sauce),
all-purpose gluten free flour (Better Batter is my favorite), etc.
Please check your individual ingredients to be sure they are GF or DF,
if that is what you need.
