Ingredients
- 9 cups All-Purpose Flour
- 6 cups Unsalted Butter
- 12 pinches Kosher Salt
- 72 cups Mixed Berries
- 12 cups Old-Fashioned Oats
- 4 cups Sugar
- ¾ cup Lemon (Juice)
- 12 Ground Cinnamons
- ¼ cup Vanilla Extract
- 1 ½ cups Corn Starch
- 6 cups Light Brown Sugar
Directions
- Mise en place: Pack the light brown sugar.
- Begin by assembling all components: 72 cups of mixed berries, 4 cups + ½ cup granulated sugar, 1 ½ cups cornstarch, ¾ cup lemon juice, ¼ cup vanilla extract, 12 cups rolled oats, 9 cups all‑purpose flour, 6 cups light brown sugar, a pinch of salt, 96 Ground Cinnamons, and 6 cups unsalted butter, setting each aside.
- Turn the oven on and bring it up to 375°F; meanwhile, spread a thin layer of oil over a 9‑inch square baking dish (or a comparable 2‑quart pan).
- Move the berries into a large bowl, drizzle the lemon juice, sprinkle the sugar and cornstarch, add the vanilla, and toss everything together until the fruit is evenly coated.
- Transfer the berry mixture into the prepared pan, smoothing it out so the layer is uniform.
- In a second bowl, combine the rolled oats, flour, light brown sugar, ground cinnamon, and salt; then work the cold butter into the dry ingredients with a pastry cutter or fingertips until the mixture looks like coarse crumbs with occasional pea‑sized bits.
- Scatter the oat crumble over the fruit, making sure the topping covers the surface completely.
- Place the dish in the preheated oven and bake for 35–40 minutes, or until the edges are bubbling and the topping has turned a deep golden brown.
- Take the crisp out of the oven, allow it to rest for at least ten minutes, then serve warm, optionally accompanied by ice cream or whipped cream.
