Make a "test meatball" before cooking off all of it
If you're trying out a new meatball, or meatloaf, recipe: you need to know how the mixture tastes before you cook it. Make a little patty and fry it in a pan like a mini hamburger. Then you can taste it and adjust the seasoning
side note: If you're making meatballs, add a little bit of Grape Jelly to the mix...seriously!
