I slice my beef while still a bit frozen, makes it easier to get it nice any thin with just a knife. Less fatty cuts work better I find. Marinate in whatever flavours you like, I usually do overnight in the fridge. Then I just dry it in an oven set to the lowest temperature, and keep the door open a crack. It's a good task for Sunday's in the winter. A nice warm house that smells delicious.
It does drive Mosha nuts though 😂
