We are staying at home because of the coronavirus outbreak. Since we are depending on a younger family member for grocery shopping we don't want to waste any food.
Because tired old grapes can't be fed to dogs, cats, or chickens, I googled "what to do with shriveled grapes" and found recipes for roasted grapes. They are delicious, as you can see from the crowd that gathered while I tried them for the first time. (Of course, dogs and cats may NOT eat grapes, but they wanted to convince me otherwise).
No more wasted grapes!
Preheat oven to 425 degrees F.
Wash and dry grapes; remove all stems. Toss them with some olive oil and sprinkle with salt and pepper.
Place on a foil-lined cookie sheet.
Roast for 35 minutes or so, stirring two or three times.
Cool and serve. I had mine on toast that was spread with cream cheese. Next time I might try peanut butter, which is also recommended.
