The Instant Pot is a multi-function gadget that pressure-cooks, slow-cooks, steams, etc. To start out, I made this braised oxtail (kkorijjim or ggorijjim, 꼬리찜) using its pressure cooking function.
Press the “Saute” button on the Instant Pot. When the pot is hot, add 1 tablespoon of canola or vegetable oil. Sear the oxtail pieces in two batches, browning all sides.
Add the vegetables.
Close the lid tightly. Press the “Meat” function, and using the “+” button, increase the time. When finished, the Instant Pot will automatically turn to the “Keep Warm” mode.
Remove the meat and vegetables from the pressure cooker. Strain the cooking liquid into a bowl to skim off the fat. Return the oxtail to the pot, and stir in the scallion and the sesame oil. Serve.
