If you’re using strawberries, remove the stems and cut the berries in halves or quarters, depending on size. Wash all the berries.
Add the berries and sugar to the inner pot. Stir to start dissolving the sugar. Add the lemon juice and orange juice concentrate (if using)
Lock the lid in place. Select Pressure Cook or Manual, and adjust the pressure to High and the time to 2 minutes. After cooking, let the pressure release naturally for 10 minutes, then quick release any remaining pressure.
Unlock the lid. Taste the berries (carefully—they’re hot) and adjust the sugar if necessary. The berries will be soupy, but will thicken up slightly as they cool. If you prefer a thicker compote, you can strain off some of the juice (it’s great mixed into sparkling water) or cook the fruit further to evaporate some of the liquid.
