Agrodolce is the Italian term for sweet and sour. In this recipe, honey provides the sweet while balsamic vinegar adds the sour. We sear only one side—the fat side—of a pork loin roast, then pressure cook it on a rack above the liquid that later becomes the sauce. Make sure your pork loin will fit comfortably in the pot and don’t trim off the fat, as it adds richness to an otherwise lean cut. A simple salad of fresh parsley, red grapes and toasted hazelnuts makes this roast an elegant meal. To save time, prep the salad ingredients while the pork cooks.
Don’t opt out of using the rack. If the pork sits directly in the liquid, the texture of the submerged areas will be affected by the vinegar’s acidity. When making the sauce, don’t add all the butter at once and make sure to reduce the sauce until glossy and full-bodied. If the sauce breaks and the butter separates, whisk in droplets of water until the sauce is once again shiny and emulsified.
