Matzah meal is a versatile ingredient that is commonly used in Jewish cooking. However, if you don't have matzah meal on hand, there are several substitutes that you can use instead. One popular option is ground matzah, which can be easily crushed into a fine powder using a food processor or rolling pin. Another alternative is to use breadcrumbs or panko, which have a similar texture and taste to matzah meal. Cornmeal and rice flour can also work in a pinch, although they may alter the flavor of the dish slightly. Whatever you choose to use, just be sure to adjust the quantity accordingly to achieve the desired texture and flavor.
