I wanted to make "instant" macaroni and cheese with whole grain macaroni, and had been wondering for years why we couldn't buy packets of cheese powder (like the ones inside the boxes of Kraft).  Was thrilled to find this product!  (One suggestion to the seller is to include basic recipe instructions.)  I did some research, and it takes about 1&1/3 cups macaroni and 1/4-1/3 cup of the powder, (plus 2 T. butter and 1/4 cup milk) to be equal to a box of Kraft.  You can jazz it up a bit by adding a few dashed of parmesan or some grated cheddar.  Maybe a little garlic and a few dashed of Tabasco, if you like it spicy.  I searched the web and found lots of tips.  This is also good sprinkled on popcorn!
