We have large (3 gallon maybe?) airtight containers with flour and sugar in them. We have separate large Tupperware containers with powdered sugar, brown sugar, and… uh… it’ like a large-grained brown sugar but loose, like regular sugar. I forget what it’s called. It’s rare that we actually use any of this stuff to any significant degree, usually just around the holidays. The flour tends to get replaced before it gets used completely. But we do it keep it on hand just in case.
We always have a container of table salt on hand as well as one of Kosher salt for baking. There’s also a jar of fleur de sel up there somewhere. Finally I have a box of pickling salt in the back of the pantry.
We have a large box of baking soda that we got for… something. I don’t remember. But it’s big, like the size of a cereal box. It’s still mostly full. We have a regular-sized can of baking powder in the cupboard as well.
Of all the stuff listed in the OP probably the smallest amount of anything we have on hand is the baking powder, which is just a regular Clabber Girl can. 8oz maybe? But I try to keep an unopened one on hand, so… well, actually a pound of that is probably still less than anything else listed.
We keep several pounds of brown and wild rice on hand, as well as assorted pastas. Beans too, although I’ve slowly transitioned to canned beans because they’re so much easier. But there’s still a few pounds of dried pinto beans in the cupboard for… reasons? We always keep a supply of both canned and frozen vegetables in the pantry/freezer.
I noted in the thread on keeping money hidden in the house that post-Covid I’ve been more diligent about stocking up and keeping stocked household essentials. Food is no exception. I’m a diabetic so I tend to eat lots of meat and veggies rather than grains and pastas, but my wife and kids like that stuff and it is good for food security. So in the pantry it goes.
We also keep a stock of canned chili, soups, and stews – basic Campbell’s stuff – on hand for those nights that we want an quick and easy meal that’s no more involved than stirring a pot. I want to start canning my own but for the moment I still get the commercial stuff.
We also continuously keep a supply of olive and canola oil, yeast, basic spices as well as mixes like Mrs. Dash, Montreal Steak and taco seasoning, peanut butter, condiments like mustard and ketchup, tea, and probably some other stuff that I’m forgetting in the cupboard at all times. I like to have an unopened bottle of pretty much everything in the cupboard always. Of course, we rotate all this stuff so no one specific thing sits in the cupboard long-term.
I always keep a collection of hot sauces on the dining room table: Tabasco (green and chipotle…mmm…), Tapatio, rooster sauce, maybe something else if it looks interesting enough when I’m at the store. I’m not much for added salt but I do keep a pepper grinder on the table.
In the freezer we try to keep a supply of ground turkey, hamburger, chicken, pork, and vegetables available. I eat a lot of chicken and pork and the rest of the family likes hamburger or ground turkey for… everything. We have ~20 cubic foot upright freezer and it’s usually stuffed full.
Despite all of the above we rarely have sweets in the kitchen. The baking supplies are more for emergencies rather than regular use. We almost never have cookies or ice cream or sodas in the house, if we want something that isn’t water my wife and kids will drink Crystal Light and I drink tea.
We do keep vegetables and fruit on hand pretty constantly but we go through that stuff so fast that I usually only buy a couple of day’s worth at a time. I do have a bunch of frozen berries in the freezer though.
My kneejerk reaction is to say “coffee” but a lot of people, younger people especially IME, tend to frequent Starbucks and similar coffee houses rather than brewing it at home. So… I don’t know if that’s still (or ever was) true.
wtf?)
