Homemade Mascarpone Cheese. Mascarpone is pretty pricey, but it takes two inexpensive ingredients and about 15 minutes heating time to make it yourself! Used in many holiday cookies, cakes, trifles, pastry, tiramisu etc. Also a creamier cream cheese substitute!
Homemade butter. Take the time to do this 10 minutes at most. Can also be done in a stand mixer, blender, or even with a hand mixer (just watch for splashing). My 5 year old son loved doing this and wants to try different mixtures with his butter :)
Revolutionary Mac Cheese -- the pasta is cooked in the milk, which forms the base for the sauce. No water, no draining... Ive been looking for this recipe for years!!! 2 cup pasta, 2 cup milk, 1 cup cheese
