Preheat your oven to 375°F (190°C) and grease an 8x8-inch baking dish.

In a medium bowl, mix the flour, sugar, cinnamon, and salt. Cut in chilled butter until it resembles coarse crumbs. Refrigerate while preparing peaches.

Score peaches, blanch in boiling water for 30 seconds, then plunge into ice bath to peel. Slice into ½-inch pieces.

Combine sliced peaches, apple juice, lemon juice, flour, sugars, and cinnamon in a large bowl. Mix gently until well coated.

Pour peach filling into the baking dish and spread evenly. Sprinkle the crisp topping over the peach mixture.

Bake for approximately 40 minutes until topping is golden brown and filling bubbles around edges.

Let cool for 10 minutes before serving, optionally top with vanilla ice cream.
