I make a lot of mixes, and use them religiously. I have both Make A Mix books and a few others that I use the recipes from(we have many favorites from them). I also buy a lot of premixed items, like cake mixes, cupcake mixes, quick bread mixes, cookie mixes, pie crust mixes, etc. I think you need to find what suits your style, cooking needs and most importantly menu plan. Buying and stocking items you will never use, even home mixes, is a waste of money, time and effort.
I just purchased 20 boxes of Duncan Hines Cupcake Mix(frosting mix included) for $1 each at Dollar Tree this week(each box makes 12 cupcakes), can't make them for that with a mix unless the items were given to me free. One style or flavor has jimmies in the mix, again cant buy them and keep the cost down on making cupcakes in the quantity I do and as often as I do. I will use these 20 boxes before the 4th of July so I am considering going back and buying 20 more.
As far as mixes go, we use the Oriental Sauce mix in the Make A Mix book at least twice a week. When I mix it up I make at least half a gallon at a time. Considering the small packets at the store of the dry mix or buying an Asian flavored sauce in the bottle, we figure we save about $71 a year using the mix. I also make a few of the meat mixes for the freezer. For many different reasons these work wonderful for us and our menu plan. I buy Bisquick or Jiffy Mix, Pancake Mix, etc.
I bake off(ground meat, liquid and bouillon)about 30 pounds of ground meat(beef, pork, chicken, turkey, lamb, ham, fishes)at a time, sometimes I flavor it for specific dishes like chili, but for the most part I leave it flavored with bouillon. I also grill chicken breasts, turkey cutlets, small steaks for sandwiches, etc., ahead of time and freeze in buns for lunches.
Again do what suits you for your menu plan or lifestyle, sometimes home made mixes just dont work.
