One of today’s Jeopardy questions gave the contestants “少し” in Romaji and asked for the related English word (skosh). That’s also the mnemonic from WaniKani, so I got it right! (My family competes to see who gets the most answers right.)
I’ve heard it in the context of cooking/food shows, but never anywhere else. I guess it’s one of those things that you infer from context and not really “know”.
