Buying food that is labeled in a foreign language that you don’t completely understand, and leaving the dictionary unused can be an adventure. (Imagine an immigrant in the US buying a tub with a picture of fried chicken on the front, and then when they got home learning that “Crisco” isn’t a brand of fried chicken, but lard.)
For example, if I am in the desert section, I am pretty safe getting any kind of プリン. I have a favorite brand of milk, no experimentation there. Butter you have to be careful with, so you don’t get some kind of seafood バーター.
