*It's important the peaches are ripe enough that they are sweet and delicious, but on the slightly-underripe side, so they do not get mushy or stick to the grill. **If you don't have the Serrano Honey Vinegar, but would like to try those flavors on this dish, sub white wine vinegar, and add 1 tablespoon of honey. Chop a serrano pepper, and leave the rings of pepper in the dressing for an hour, then remove before serving. These will leave a subtly spicy flavor to the dresing similar to the infused vinegar I used.
