Webster’s defines pie as a dessert consisting of a filling in a pastry shell […].
[/third grade voice]
A cake is “a sweet baked food made from a dough or batter”. A cheesecake is not made from a dough or batter, it is a filling in a pastry shell. Ergo, it is not a cake. It is a pie. Why isn’t cheesecake called cheesepie?
cake ( P ) Pronunciation Key (kk)
n. 1. A sweet baked food made of flour, liquid, eggs, and other ingredients, such as raising agents and flavorings.
Because it is a CAKE!
The other ingredients being cheese etc.
It is not (usually) in a shell but sits on a base of cookie crumbs, no sides.
And it is called a cheese cake, because it is called a cheese cake, that’s what it is.
My guess would be because pies were originally savoury and the pastry was only a means to deliver the filling, so a cheesepie would be construed as some melted cheesy savoury delight.
Ricotta cheese pie is a pie even though it’s made very similarly to a cream cheese cheesecake.
“Pastry shell” for a cheesecake? An abomination. Cheesecake should either have no crust or, yum, a sweet buttery graham cracker crust. Possibly even an Oreo crust. But a pastry shell crust, ick.
Referring to the dish that the OP is talking about as “cheesecake” goes back to at least the seventeenth century. A recipe for such a food, however, goes all the way back to the fourteenth century.
I seem to remember finding a recipe for something called a “chessecake” but the heck if I can find it now.
The use of the word “cake” to mean a sweet, bready food goes all the way back to Chaucer and probably before. “Pie” (pye, actually) was in use at the same time, though generally seems to refer to a meat pie rather than a sweet one.
As for why it’s called cheesecake, I’d imagine it would have something to do with a pie being savoury, rather than sweet, as don’t ask said. That and the fact that language has never played by dictionary rules.
A pastry shell (part of OP’s definition of pie) implies that there’s a top, like in most pies (‘shell’ is defined by M-W as a thin, usually spherical layer or surface enclosing a space or surrounding an object).
How many pies have the fruit right out there, with no top crust? None, as the OED calls this treat a custard (though the word has come to mean something else), but limits a custard to having a meat or fruit filling. Cheese is neither (duh).
So far, technically, it’s not a pie, or a custard. The OP doesn’t define cake, just pie (good going?). Here’s what the OED calls cake -
which is pretty goddamn general, and I would interpret to include cheesecake or practically any other sweet baked mass. Considering the many varieties cheesecake can come in, it looks pretty damn cakelike a fair amount of the time.
It’s certainly no pastry, as it’s not made of "flour moistened with water or milk and kneaded, dough; esp. (now only) with addition of butter, lard, suet, or the like."
If that’s not good enough, be nice and general and call it cheese confection. VERY APPEALING!@
There are good reasons to think of cheesecakes as custard pies. You don’t mix them like a cake batter (i.e. cream butter and sugar, alternate adding the wet and dry ingredients). Also, you don’t bake it like a cake. Most cheesecake recipes call for baking it in a water bath, just like creme brulee or creme caramel or any other baked custard.
