INGREDIENT NOTES

Puff Pastry – Use all-butter puff pastry for the flakiest, richest layers. Keep it chilled until you’re ready to work with it.

Blackberries – Fresh blackberries provide the brightest flavor, but frozen berries work just as well. If using frozen, there’s no need to thaw them first.

Granulated Sugar – Sweetens the berries while allowing their natural flavor to shine.

Cornstarch – Thickens the blackberry filling so it stays inside the pastry instead of leaking during baking.

Lemon Juice – Brightens the filling and balances the sweetness with a touch of freshness.

Vanilla Extract – Adds warmth and enhances the berry flavor.

Egg Wash – Gives the pastries a beautifully shiny, deep golden finish.

Powdered Sugar – A simple finishing touch that makes the pastries look elegant and adds just the right amount of sweetness.
