Frozen and canned fruits: You can also use frozen peaches or canned peaches. Frozen peaches do not need to be defrosted; you can use ½ cup total sugar in the filling, as they may be more acidic. For canned peaches, omit the sugar or use ¼ cup sugar in the filling. You can also use frozen blueberries; you do not need to defrost them.
Peeling tips: To quickly peel peaches, plunge them into boiling water for 45 seconds, then, when cool enough to handle, peel the skins off with your fingers (see How to Peel Peaches). Or, if they're ripe enough, you can peel the skins off with your fingers and a paring knife as you slice them.
Flavor options: Add ¼ teaspoon orange zest, ⅛ to ¼ teaspoon almond extract, or 2 tablespoons bourbon or amaretto to the filling for a more complex flavor. Substitute fresh or frozen blackberries, strawberries, or raspberries for the berries.
Filling ideas: Top with vanilla ice cream, whipped cream, sweetened Greek yogurt, or crème fraîche. Or make whipped cream with alcohol, like bourbon or amaretto whipped cream, which pairs well with the fruit.
