I recently picked up a grinder attachment for the Kitchenaid, so I thought I'd try my hand at grinding my own meat for burgers. First attempt was with a 3:1 ratio of ground to flank. It looked (and smelled) beautiful. I seasoned with just salt and pepper and grilled over a very hot hardwood charcoal fire. One of the best tasting burgers I've made, but not the perfect burger. Not yet. For one thing, they need to be bigger for more bun coverage. (And I need to take better photos, bah.)
