As Lab Lemming pointed out, the graham cracker crust I made for my pie last weekend cannot be represented on the ternary phase diagram for traditional pie crust. But that doesn’t mean it is somehow illegitimate or unsciencey! See, look at all this science:
In addition to being simpler to prepare, the graham cracker crust is delicious over a much larger range of compositions than a traditional pie crust.
I will have another pie posted later this week, but the rate-limiting ingredient is still equilibrating with ethelyene gas in a bag on my kitchen table.
