Using the saute function on your Instant Pot, melt some butter and let the couscous heat and get some flavor before cooking.
It doesn't take long to prepare couscous with an electric pressure cooker. Set your timer for 7 minutes and let the pressure build.
There may still be some liquid with the couscous when it's done. This is okay! Turn the pot to the KEEP WARM function, and stir until the rest of the liquid has evaporated.
