Does this need to be cooked? Or can it be eaten as is?

So… my mother-in-law bought this when she came with us on the last grocery run and said “oooo this is nice.” It’s been sitting in the fridge (not freezer) and neither my wife or I know how it should be consumed lol she’s half German and half Korean and isn’t familiar with traditional snacks or dishes so here we are asking on reddit! She just forked one out and ate it straight from the jar and commented “omg is so salty” 😂 Thank you in advance!
