We’re all drowning in Thanksgiving tips and to-do’s but here’s one more and it’s only three words: mascarpone whipped cream. I bet you’ll never again put plain whipped cream on your pies after you sample this luscious alternative. It’s not only a tastier dessert topping, it’s more stable, so you can whip it up hours ahead and it won’t weep. I add a splash of Jamaican rum for its brown-sugar flavor, but you can stop with vanilla extract if you prefer.
