So something I enjoy doing on our travels is staying in apartments and cooking every once in awhile - eating out all the tiem gets kinda boring and expensive.
So I have picked up a few 'oops' things at the grocery store...these both happened last year but I'm sure something else might pop into my head.
In Prague we popped into a grocery to get a few snacks to take back to the hotel. We usually like to have a pop or juice in the evening so I picked up this bottle of brightly coloured orange liquid assuming it was a fruit juice. Got back to the room, poured a glass, took a big gulp - wow, that's really, uh, thick. Then I realized it was meant to be mixed with water or seltzer. It tasted pretty good once I did that!
In Bolzano I wanted to fry up some chicken cutlets but no butter in the apartment - we picked up what I thought was little silver cubes of individually wrapped butter at the grocery - it was right beside all the other butter and I didn't want to buy a lot since we wouldn't be taking it with us. Get back to the room and unwrap it - what is this beige looking stuff? I smell it - that's not butter. Did a google translate - turned out it was cubes of some kind of yeast. Luckily the grocery was a few minutes walk away so was easily able to correct that error.
So what interesting mistakes have you made at the grocery store?
