CHill's hamburger rub #3:
per pound of hamburger,
1/2 tsp salt
1/2 tsp pepper
1/2 tsp onion powder
1/2 tsp chili powder
1/4 tsp celery seed
1/8 tsp ground cardamom seed (or other sweetish aromatic, like garam masala)
1/8 tsp cayenne or red pepper flakes
mix rub into meat with yellow mustard if needed, form into patties, let sit while coals get started, grill and eat
notes:
tasty on a bun with ketchup and mustard
a bit stronger flavored eating the meat plain, was fairly mellow/complementary with the bun and condiments
I was trying to emulate the flavor of the nice burger carts in Portland, like the Brunch Box, which often have a subtle flavor to them which marries well with grilled onions and ketchup and mustard. This recipe is close but not exact. Salt, pepper, onion is a good place to start for a burger rub. Depending on what you're looking for, you could take it in other directions with the salt pepper onion base, more chili powder and heat for a southwestern flavor, coriander and dill for Montreal steak flavor, garlic ginger and five spice for asian flavor...
