No buttermilk? You can make your buttermilk substitute at home. Just add 1 teaspoon of white vinegar or lemon juice to a liquid measuring cup, then add enough cold whole milk to reach 1/2 cup. Give it a good stir and let it sit for 5 minutes. Your homemade buttermilk is now ready to use in your recipe, even if it appears slightly curdled. Peeling peaches: I do like to peel my peaches. To do this, easily cut a star shape on the bottom of the peach and place it in boiling water for 30 seconds, then remove it to a bowl of ice water. The skin will peel off easily.
