If you come across muscat grapes in your grocery store, grab them up like there's no tomorrow. Elbow that little old lady out of the produce aisle and be greedy. I'm being serious. These are, without a doubt, the best grapes I've ever eaten. Rosy and golden in color, they taste like a musky, slightly sweet glass of white wine, which makes sense because that is what they are primarily used for, especially sparkling wines like Asti Spumante.
Use them to fancy up a cheese plate, roast them with pork, freeze them for an icy snack, or just eat a pound of them straight out of the bag, like I did at work last week, dribbling juice all over my keyboard. Don't say I didn't warn you.
