Let it chill inside the cooker with the steam off, giving the seeds time to swell and thicken up—about 4 hours or even overnight if you want it thicker. When it’s ready, do a quick release to open the lid carefully so you don’t lose that creamy texture. Give the pudding a good stir, taste it, then add a little more maple syrup if you want it sweeter. Garnish with fresh lemon zest or maybe some fruit on top. You’re done and ready for a good spoonful.
