Essential Ingredient Guide
- Fresh blueberries: Choose plump, deep‑blue berries; they hold their shape and add juiciness.
- All‑purpose flour: Sifts well for a tender crumb; you can use whole‑wheat for a nutty twist.
- Unsalted butter: Cold, cubed butter creates a flaky texture in the crumble topping.
- Brown sugar: Adds caramel notes that balance the fruit’s acidity.
- Lemon zest: A pinch of zest brightens the flavor, especially with blueberries.
- Vanilla extract: Just a splash enhances the overall warmth without overpowering.
Complete Cooking Process

Wash berries, pat dry, and toss with a little sugar and zest; chill butter for topping.
