So - salted beef like the kosher butchers sell would be close?

A sailing standby was a couple of tins of corned beef with onions, carrots and potatoes, plus anything else in the locker, chopped and cooked up in a pressure cooker with a couple of pints of water and a couple of oxo cubes for twenty minutes.

There was even a standard accessory of a gymballed holder for a pressure cooker to hold it level and safely clamped over the flame even in a rough sea.
