My list is fairly similar to yours. I used to do a 2:1 parm/romano grate for topping salads and if anyone wanted shreds atop pasta, and lately (last few years) this is a 2:1:1 parm/romano/asiago. Same as you with the cotija, it’s a great crumbling cheese.
I like to use a mix of fontina and Monterrey Jack shredded into various casseroles, and also use them with mozz shredded into stuff like baked ziti or lasagna rather than just using ricotta and mozz alone.
Both store-bought (always) and home-made (when I get the urge) sour cream and crema. Buttermilk I get only for specific recipes and for making sour cream. So one of my most frequent wastes is tossing sometimes as much as half the buttermilk container; even if I’ve made both buttermilk biscuits or pancakes and sour some cream, I rarely get through a whole quart.
I keep several pre-shreds on hand but these are mainly now used when the kids visit for their breakfast tacos or quesadillas.
Always have ghee plus separately I save all the toasted milk solids from the ghee making to a small container with a bit of the ghee covering the solids - these are good for a nice savory addition to eggs and other stuff.
I’ve got one daughter who is gluten free and sort of vegetarian (she will eat dairy, and shrimp) and she comes home about twice a month, so I make paneer the day before she gets here to make paneer curries. Otherwise, I don’t usually make paneer for just my wife and me, unless she gets a hankering for butter paneer (identical to butter chicken, just with paneer).
Chunk whole milk mozz and fresh mozz nearly always in the fridge for pizzas and (much more rarely) caprese salad.
Same here. Most of the extras are just for slicing and eating, though, rather than for cooking. My wife says I over-buy, and I guess I do, but it’s hard to pass up good deals. And it’s rare that any will be thrown out (sometimes I do have to trim a bit of surface mold), because 3 of the 4 kids visit pretty regularly and they’re all cheese hounds. And 2 of them don’t have great grocery options nearby so they’re often grabbing an unopened package on the way out the door heading back home.
My wife got me these nifty fridge organizers and I’ve got 3 of them in there for the 35 different kinds of cheese.
