Fruit compotes, jams, and marmalades are real easy to make with sous vide. Simply put some fruit, with any pits or inedible skin removed, in a bag with some sugar and acid then cook it up to an hour or two and you are good to go.
For a thicker jam you can also throw in some pectin as well. You can make these either in sous vide bags or in filled Mason jars, but note that the end result needs to be refrigerated and can't be stored in your cabinet.
Preheat a water bath to 183°F (83.9°C).
Combine all the ingredients in a sous vide bag and seal. Cook for 30 to 60 minutes.
Once cooked, remove the blueberry compote from the sous vide bag and lightly mash.
Place a spoonful of the oatmeal in a bowl and top with the blueberry compote. Add a few mint leaves and fresh blueberries then serve.
