Crumble Topping

Crumble topping is a mixture of flour, fat and sugar that is scattered over fruit or another preparation before baking. The mixture bakes into a crisp, crumbly layer that contrasts with the softer filling. Oats, nuts, spices or other dry ingredients may be added depending on the style.

Basic components

• Flour: provides structure and absorbs some of the fat.
• Butter: binds the mixture and contributes flavour and crispness.
• Sugar: sweetens and helps the topping brown.
• Optional additions: oats, chopped nuts, cinnamon, citrus zest or other spices.

How to prepare crumble

Rub cold butter into the dry ingredients until the mixture forms irregular crumbs. Avoid working it into a smooth dough unless the recipe specifically calls for that texture. Scatter the topping evenly over the prepared fruit and bake until the filling is cooked and the topping is golden.

Uses beyond fruit crumble

Crumble topping is used on apple, berry and stone-fruit desserts, as well as on muffins, coffee cakes and certain baked puddings. A savoury crumb can be made by adjusting or omitting sugar and adding herbs, cheese, nuts or seasoning.

Chef’s tip: Keep the butter cold and chill the finished crumbs before baking if the kitchen is warm. Use a light hand when scattering so the topping stays irregular and crisp rather than forming a dense layer.
