Oatmeal

Shake jars immediately after cooking to distribute starch and keep oats creamy.

Add chia or flax seeds after the bath so they don’t thicken excessively during cooking.

Store jars without toppings for up to 5 days; add fruit/nuts when serving.

Line jars with parchment if you plan to unmold and slice.

Let oats cool fully before cutting so they hold their shape.

For sweet versions, stir chocolate chips or dried fruit after cooking so they stay intact.
