Mix dry ingredients, add wet ingredients
This recipe makes 4 single crusts, and it freezes very well. What I usually do is mix it all up, divide it into 4 in my bowl with a knife, and put what I'm not going to use that day into 1qt size freezer baggies. The other thing I like about it, then, is that when I do want to bake a pie, I often have crust ready, and it defrosts quite quickly compared to some other things. You may not have enough room in your freezer to keep stuff (I can't remember how much space you've got), but they don't take up a ton of room, taste great, and you don't have to guess with the water!
