Method

1. Prepare tangerine peel: Use a knife to carefully scrape away most of the white pith on the inside of the peel. The while pith is bitter, so we don’t want that.
2. Prepare lotus seed (if using): Soak lotus seeds for 30 minutes. Split each into half and remove the black germ in between.
3. Pressure Cook: Add the red beans, lotus seeds, tangerine peel and water into the pot. Pressure cook on High for 20 minutes. Quick release when it is ready.
4. Prepare oats: Meanwhile, add some (boiling) hot water to the oats. Stir and set aside.
5. Add remaining ingredients: Open Pressure Cooker lid. By now, the red beans would have softened dramatically (see below). Add oats, longan and sugar.
6. Saute on HIGH for 5 to 10 minutes. Stir. Enjoy! Serve hot or cold. The dessert will thicken further as it cools.
