Definition of a "half glass?"

Question

I'm making oven baked caponata and the recipe calls for a half glass of vinegar. No clue how many ounces to a "glass."

Answer 1

From my years of cooking, I would guess this to be about 4 oz. or 1/4 C. as we sometimes used a small 8 oz. juice glass for measuring and half a glass would be half of that or 4 oz = 1/4 C., especially with vinegar, Other than pickles I could not imagine a recipe using more vinegar than that. Hope this is helpful.
