I’ve recently been doing some instant coffee with milk and it is really fucking good. Around February I wanted a bit of a classic snack the way my grandparents would, some sweet bread with instant coffee. So I got myself some. I had forgotten the powdered creamer, so I used milk. I was pleasantly surprised.
I worked in a brewery where I could just tap off hot water from the 2000L kettle. We would all just put a splash of hot water in a tbsp of instant coffee then top it up with oat milk or whatever is in the fridge. Not beating the super fancy stuff from the former commercial coffee machine shop next door used to make us daily in return for a case each canning session, but way better than any of the chain shops in the area.
