Dice up onions and red peppers, dicing the onions slightly finer than the red peppers.
Place onions and peppers into Instant Pot cooking pot.
Add butter. (Kosher people, if you are making this dish with a meat meal, use margarine instead.)
Add salt, ground cinnamon, ground allspice and ground cardamom.
Add in cranberries and raisins.
Pour in orange juice and mix to combine.
Sprinkle in couscous and do not mix.
Lock on lid and close pressure valve. Cook at high pressure (most machines default to high) for 0 minutes. Yes, 0 is correct. The time it takes the pot to come up to pressure and then release, is the perfect time for couscous.
When beep sounds, wait 15 minutes and then release the rest of the pressure (if any is left).
Remove lid and fluff with a fork.
If adding nuts, mix them in after fluffing, otherwise, move on to the mint.
Stack mint leaves with the veins horizontal to you. Tightly roll up the leaves using the long side. Take a sharp knife and cut vertically (rolled leaves should still be horizontal) 4-5 times to make 4-5 rolls. Unroll and you will have ribbons.
Plate couscous and garnish with ribbons of mint leaves. If leaving couscous inside the pressure cooker, sprinkle mint ribbons over the top.
Many of the ingredients can be switched to a totally different flavor. Currents give great color and flavor and can be used in place of cranberries. Any combination of fruit with the orange juice is delicious. For a more savory flavor, try using chicken or beef broth in place of the orange juice.Couscous absorbs the liquid quite quickly, so make sure to start the pressure cooker as soon as you lock on the lid. If for some reason, the pot does not come to pressure, do not worry. Allow the pot to sit closed for 30 minutes. This is enough time for the pot to become hot and allow the couscous to cook on warm.
To substitute whole spices for ground.
If making for your family and you are used to using and eating around whole spices, heat Instant Pot completely and add a drop of oil and butter. Drop one whole cinnamon stick, 6 whole allspice and 5 whole cardamom into pot. Heat for about two minutes to toast. Then continue on with recipe.
If making for a pot luck, I suggest leaving out nuts, so that you don't need to worry about nut allergies. If cooking for people who you know for sure do not have nut allergies, add 1/2 cup of chopped pistachio nuts or whole pine nuts to couscous after fluffing and then gently mix to combine.
