Rinse the rice under cold water to remove excess starch.

In the crock pot, combine the rinsed rice, whole milk, sugar, vanilla extract, salt, and ground cinnamon.

If using, stir in the raisins.

Cover the crock pot and set it on low for about 4 hours.

Gently stir the pudding every hour if possible to prevent sticking.

After 4 hours, check that the rice pudding is thick and creamy.

Stir again before serving warm, optionally adding a sprinkle of cinnamon or honey.

If there are leftovers, let them cool before storing in an airtight container.
