Out of breadcrumbs? Use the bread already in your kitchen
A gratin is ready for the oven, but the breadcrumb packet is empty. Before shopping, check your bread supply. A dry piece can provide a useful topping; the aim is a finish that suits the dish, not an exact copy of every packaged product.
Start with bread that is still fit to eat
The French Ministry of Agriculture lists breadcrumbs as one use for dry bread. Use only bread that is still fit to eat, with no mould or signs of spoilage; cooking is not a way to rescue spoiled bread. For a first attempt, prepare just enough for the meal rather than creating another unused stock.
Match the texture to the dish
Pulse dry bread in a suitable appliance. Follow its instructions and do not force it through large, very hard pieces. Keep slightly uneven crumbs for a textured gratin topping, or grind finer for a more even layer. Dense homemade crumbs will not necessarily reproduce light panko.
Use a light topping and watch the colour
Scatter a thin layer over the surface and fill gaps only as needed. Follow your dish’s cooking instructions while watching the topping. Breadcrumbs alone will not fix excess liquid in a wet gratin. Include any added oil or cheese when calculating the recipe.
Test small amounts when crumbs provide structure
Binding a mixture is different from decorating its surface. Bread moisture and crumb size affect the result. Test a small amount, mix and observe before adding more. Avoid universal spoon-for-spoon substitutions between products of different densities. Record the weight and outcome to reproduce your version.
Save a purchase without assuming identical macros
The benefit is using something already bought. Buying special bread solely for crumbs is not automatically cheaper; compare useful quantities. Plain bread, seeded bread and seasoned breadcrumbs differ. Adjust estimated macros to the bread and weight used.
