If an American recipe calls for "cube steak"............

[MerryChipmonkAndAHappyNewey]

What do I use? I had thought it was cubed chuck steak/round steak but after looking up the definition, I'm not sure if I should be using sirloin/fillet instead! Anyone know?

looks like it's rump, just tenderised

If it's a long slow recipe I'd use stewing / braising steak; if it's a quick-cooked recipe I'd use rump (rarely buy fillet or sirloin myself as rump is so much tastier)

It's rump.

aha

also known as 'minute steak'

It is tough. You need to marinate that a while.

Thank you! Right now the thought of fiercely pounding it myself sounds quite tempting! Could do with releasing some aggression!

MANY memories of minute steak. It is tough, trust me. Soak it in marinade a while, then beat the hell out of it. It's like skirt steak/fajitas.
