Place trivet in the instant pot and ribs on top of the trivet in a circular fashion. Add water, liquid smoke, juice from one orange and the leftover orange slices, into the instant pot. Secure lid and set on manual pressure at High for 25 minutes. Allow for natural release for an additional 15 minutes.
While the ribs are cooking, combine remaining ingredients into a small pot on the stove. Whisk and cook ingredients over medium-low heat for approximately 15 minutes. Flavors will come together, onions will cook through, and the sauce will become thicker. Remove from heat and await ribs.

Recipe Tips
If the back of the ribs has a membrane, do your best to remove that prior to seasoning the ribs. With the bones facing up, slide your finger or a butter knife under the membrane between two rib bones until you can grip the membrane with a paper towel and pull it off.
Season the ribs with a dry rub. A dry rub is best for these ribs because it will infuse it with a lot of flavor as it cooks and it won't wash away while it steams in the Instant Pot.
Pressure cook the ribs rolled in a circle. They won't cook evenly if you cut them and stack them.
You can sauté the onions first in some butter for more depth of flavor.
Broil the ribs for a few minutes to crisp the top and boost the flavor of the barbecue sauce. Use the middle position in your oven when broiling for the best results.
This recipe works for one or two sets of ribs without adjusting the sauce quantities. Simply add a second set of ribs coiled in the Instant Pot.
It's best to use a 6 QT or larger Instant Pot.
