I love the electric grinder I bought from ALDI like 5 years ago.
Still going strong with being used at least once per week. The hand grinder was such a pain to clean.
The secret to making burgers is just fresh ground beef & a long sheet of cling wrap to squish them between. It sounds simple but it was a game changer for me.
I don't like the shit Australians put in their burgers. If you need to add egg, you're doing it wrong.
