Sometimes you want to make grandma's recipe and she wrote one can and isn't around anymore to ask questions about the size of the can.

But if you head over to c/cooking you will see you can't even use cans as a unit of measurement in most of the things I cook.

Or a box

I have a recipe that's cans cream of mushroom, with equal parts rice and milk. The can size does not matter because it is about the ratio.

Hell that's how most of my recipes are. I don't measure like 80% of my cooking. When you're baking yeah of course. But just cooking normally? Measuring is for losers. How many ounces of onions? How many you fucking got? Garlic? There's no measurement of garlic it's as much as you can. That's how I cook. Eyeball that shit and have a spoon for tasting.

Also cans are usually you know measured pretty well themselves actually. 8 oz can hold 8 oz. Not like it's any more holy to use an 8 oz measuring cup than an 8 oz can.

I haven't seen those yet, but yeah, seems they figured it out.

It's a shortcut

The levener is baking powder and baking soda. Rhese are cheap ingredients a container of each can last years.

Those mixes are easy to replicate. If the mix changing prevents them from making it from scratch they were never a baker. Anymore than making me making a Mac and cheeses makes me a chef because I added some sliced cheddar.

These mixes were created for convenience. They did not create the concepts behind the end product. They are made with magical difficult to source ingredients.

Well, 1/6 of an egg either way isn’t going to change anything.
