Crackers. First, yes, you need the crackers; they help bind the burgers together. I used Trader Joe’s Golden Rounds, which is what was in the house. The closest thing to this is Ritz crackers, but plain Saltines or other softish crackers would also work just fine. I would NOT opt for really crisp or hard crackers—Triscuits, Ryvita or those hard thin grim whole grain wafers would be wrong wrong wrong.
