What does Pork Tenderloin with Hot Fanny Sauce taste like? A little sweet, a little spicy — a little Mexican, because of the jalapeños and poblanos — but not too hot and very, very flavorful. This is a great way to sauce a tender cut of pork. The sweet potato mashers we’re serving with it, combined with a bit of chopped pecans and topped with marshmallows, are light as air. We added another side to the dish as well: a cool and creamy bit of coleslaw to play off the spiciness of the pork. Delicious? We think so.
