Indeed, you can truly taste the tomato in these fiery red cupcakes. Not only that, but the unassuming beige frosting holds yet another surprise taste sensation: A tangy punch of balsamic vinegar, tempered by the sweetness of the rich and fluffy matrix that contains it. Trust me, it’s one of those crazy things that you’ve just got to taste to believe. Although it may sound like an edible acid burn, that small splash is just enough to brighten up the whole dessert.
