Rinse your dry azuki beans in cool water and drain completely. Transfer to your Instant Pot or pressure cooker.
Add water, make sure the lid is on the sealing function and cook using the "beans" setting. Once ready, let pressure release naturally for 10 minutes, then force release.
Drain the cooked beans and return them to the instant pot container. Add your sugar and stir until all of the sugar dissolves and the beans thicken slightly. You can also let the mixture sit and cool for 10-15 minutes.
Transfer the mixture into a food processor and blend until completely smooth. Pour into a container and let chill in the fridge until completely cool and firm.
