Step 1

Heat olive oil on sauté setting. When hot, add chopped onion.  Cook for a few minutes to soften then add garlic, cook for 30 seconds more.  Turn off sauté function.

Step 2

Add the stock, apple cider vinegar, sugar and crushed red pepper; stir to combine.  Season with a little salt and pepper.  Lay in the ham shanks and cover the top with chopped collard greens.  Push down the collards to submerge, be careful to stay below the fill line.

Step 3

Seal pressure cooker and set timer for 30 minutes on high pressure.  When finished, let pot naturally release for 15 minutes.  Release any remaining pressure and open, remove ham shanks and bones to board. Cut meat into bite size pieces and return to pot.  Put in serving bowl with cooking liquid and serve.  Don't forget the cornbread!
