Any one think that there can TOO much beef for a hamburger.
1/4 lbs, is a bit skimpy (too easily overwhelmed by the lettuce and tomatoes and not enough counter-balance to the bun)
1/2 lbs. is good, not great, depending on the toppings, dressings, etc..
1/3 lbs. is just right (for me anyway) and provides the proper balance between savory patty mouth feel to the cool crisp lettuce, tomatoes and sweet/saltiness of the ketchup, mustard, pickles, etc.
1 lbs. is too much meat, it's like you ordered meatloaf and they threw in the buns as an after thought.
Any one else have a preference?
