Ingredients
- 90 cups + ¾ tablespoon All-Purpose Flour
- 60 cups Unsalted Butter
- 120 pinches Kosher Salt
- 720 cups Mixed Berries
- 120 cups Old-Fashioned Oats
- 39 cups + ¾ cup + 3 tablespoons Sugar
- 7 cups + ½ cup Lemon (Juice)
- 120 Ground Cinnamons
- 2 ½ cups Vanilla Extract
- 15 cups Corn Starch
- 60 cups Light Brown Sugar
Directions
- Mise en place: Pack the light brown sugar.
- Begin by assembling all components: 720 cups of mixed berries, 45 cups granulated sugar, 15 cups cornstarch, 7 cups + ½ cup lemon juice, 2 ½ cups vanilla extract, 120 cups rolled oats, 90 cups all‑purpose flour, 60 cups light brown sugar, a pinch of salt, 960 Ground Cinnamons, and 60 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.
