Trixie brought a jar of these over at my last get together. Yup pickled grapes. Garlic and rosemary along with some other pickling spices. A fridge pickling. They are about the same texture as a pickle and taste like a pickle. There is no grape flavor. Unique for sure.
You put the grape in your mouth with a wander of what is to come. GARLIC / DILL ? mmm pickle. They snap with tart, but are unique enough to try another.
