If you are making stuffing or adding breading to meat or fish, your recipe will likely call for breadcrumbs. Breadcrumbs are exactly what they sound like: small pieces of bread that have been crushed to make crumbs. You can buy breadcrumbs at the grocery store, but if you need them in a pinch or if you want to make your own at home, they are easy to make. If you don't have any bread, breadcrumbs can be made with many different crackers, including Ritz crackers.
Pulse the Ritz crackers in a food processor. If you don't have a food processor, put the crackers in a plastic zip-top bag, and use either a heavy pan or rolling pin to crush them.
Check the texture of the cracker crumbs to make sure they're even. Continue pulsing or crushing until the texture is uniform. Depending on the recipe, you may want a coarse or fine texture for the crackers.
Add seasoning or other accompaniments. Some recipes will direct you to add dried herbs or spices to the Ritz breadcrumbs before you use them in your dish.
