Yeah, definitely. I would argue that “nutritious” should mean “can I live off of this?”. From that context, you need high calorie, balanced macros, and no glaringly missing micronutrients.
I wonder if anyone’s made the soup version of completefoods.co (which is like a DIY soylent-making site).

From what i understand “cottage cheese” is a cheese made from milk treated with rennet, lightly strained, and mixed with a little bit of cream. I’m sure there’s regional variation in the terminology and process.
From like 2 minutes of searching online, I seems like what people call “dry cottage cheese” is basically just what I described. Heat milk, acidify it, and strain. Typically what I do is strain it with a cloth until it’s fairly dry, then I’ll mix back in some of the whey until I get the texture I like.
The fancier version involves fermentation with bacterial cultures to create the necessary acid, but that’s not something you are going to do with a half jug of milk you want to just use up before it goes bad.
