3 large bunches seedless grapes, preferably mixed colors, stemmed
Vegetable or canola oil, for greasing
Directions
Preheat oven to 225 degrees F . Very lightly grease 2 rimmed baking sheets with oil, then scatter grapes all over. Bake, checking periodically for doneness, until grapes are nicely shriveled and semi-dried but still slightly plump, about 4 hours . Let cool. Use a thin metal spatula to free any grapes that are stuck to the baking sheet. The dried grapes can be refrigerated in a sealed container for about 3 weeks. .
