Turn the Ninja Foodi on sear/saute medium heat and add the raspberry preserves, brown sugar, lemon juice, apple cider vinegar and spices. Heat and stir to combine. When the preserves and sugar have melted and the spices are incorporated, turn the Ninja Foodi off and pour into a medium size bowl. Allow to cool. You can put it in the fridge to cool.
This will make about 2 cups of Raspberry Glaze which is enough for several racks of ribs. Store in an air tight container in the fridge until you are ready to use it again.
For the Ribs
Remove the membrane from the back of the ribs. The easiest way to do this is to lift up a small piece of the membrane and grab it with a paper towel, then pull the membrane off. You can watch how I do this in the video below the recipe.
Mix up the rub ingredients and coat both sides of the ribs with a generous amount of rub. The rub recipe makes enough for 2-3 racks of ribs and can be stored in a sealed container.
Cut the rack of ribs in half and rub generously with the rub. You can do this ahead of time and wrap the rubbed ribs in plastic wrap and store in the fridge overnight.
Place ½ cup of liquid smoke and ½ cup of apple cider vinegar into the inner pot. You can also use beer, water, or a combination. As long as you have 1 cup of thin liquid you will be fine.
Place the ribs in the basket that came with the Ninja Foodi. I place them on their side. Be sure to leave enough clearance for the pressure cooker lid.
Turn the Ninja Foodi on high pressure for 18 minutes. Don't forget to turn the valve to seal. When the cooking time is up, allow to natural release for 10 minutes and then manually release the remaining pressure. Dump the liquid.
Lay the ribs onto the rack in the low position. Brush with the raspberry glaze. Turn the Ninja Foodi to the AC function on 400° F and Air Crisp for 10-20 minutes. Reapply the glaze every few minutes.
Nutritional information was calculated using all of the rub and all of the raspberry sauce. It is doubtful that you will use all of it with one rack of ribs.
