Cook grits according to package directions to yield four cups of cooked grits.

While the grits are cooking you'll have plenty of time to prepare the stewed blackberries.

Heat a small sauce pan over medium heat.

Add the fresh blackberries and sugar.

Add the water to a liquid measuring cup and add the cornstarch. Mix to combine into a slurry mixture.

Add the slurry mixture to the sauce pan.

Cook 3-4 minutes. That's plenty of time to stew the berries. Remove from heat and reserve until ready to serve.

Add cooked grits to serving bowls and top with some of the stewed blackberries.
