1. Turn on the Instant Pot and set it to “Saute” – this will heat of the pot so it will reach pressure quicker when it’s time to cook.
2. Combine the Dry Rub ingredients using a fork or small whisk – try to break up any little chunks of seasoning so everything is evenly distributed.
3. Remove the membrane from the underside of the ribs if there’s one still intact. (This is a thin layer of fat/tissue on the side close to the bones – removing this will allow the seasonings to better permeate the ribs.)
4. Pat the ribs dry using paper towel – you want to make sure to remove the excess moisture.
5. Cut each rib rack into 3 sections so they’ll fit nicely into the Instant Pot.
6. Using your hands, rub the dry rub seasonings into the ribs, making sure to concentrate on the meatiest sides. You can rubs them together as well to make sure the ribs are evening coated. Allow the dry rub to soak into the ribs while you go onto the next step.
7. Add 1/2 cup of BBQ sauce and cider vinegar to the Instant Pot (or pressure cooker) and allow it to warm for a minute or so.
8. Now place the ribs, meat side down, into the instant pot on top of the sauce. Don’t worry if the ribs are not touching all the sauce – it’ll all work out in the end – promise! 😀
9. Put the lid on the Instant Pot. Turn off the “Saute” function.
10. Select the “Meat/Stew” function and set to cook for 35 minutes.
11. Once the timer on the Instant Pot beeps, let it sit for 5 minutes. Then release the pressure.
12. Remove the ribs to a rectangular metal baking pan, lined with aluminum foil.
13. Turn on the “Saute” feature, add the reserved 1/2 cup of BBQ sauce, stir and allow to reduce for about 5 minutes (while you do the next step).
14. Using strong kitchen scissors or a knife, separate the ribs into individual pieces.
15. Once the sauce has reduced at least 5 minutes (or more if you like), pour it over the ribs.
16. Place into the oven to broil for 10 minutes.

Enjoy!
