One of the lads in our men's kitchen suggested using these bacon chops from Aldi's instead of a hock. Seeing it will be the last soup now the warmer weather is due, I gave it a go. Not quite as good as a hock (but half the price). Probably needed one or two of those Knorr ham stock cubes - don't think we have them here in Oz.
Wife reckons the shredded meat from the hock was better (I diced the chops after cooking). I think the chops might have been a wee bit too lean. Might try them with a proper fry-up one day.
