We are too prone to make everything around a store bought beef patty, a mistake in my opinion. Make it yourself; it takes more time but the results are worth it.
Yes, I’ve recently discovered that buying the meat fresh is the better alternative.
The problem with hand shaped patties is they are usually mounded in the middle so the lettuce/tomatoes/pickles fall off. The trick to getting a flat patty is to smoosh a ball of meat between a flat bottomed bowl and a plate or cutting board. Mix the meat and seasonings in the flat bottomed bowl to save a dirty dish.
About the only ground meat here is the 70% and it’s $16 a 5 lb tube. Yikes! It wasn’t that long ago it was $14 for a 10 lb tube.
