In a medium-sized pot, combine the cranberries, sugar, and water.

Place the pot on the stove over medium-high heat and bring the mixture to a boil, stirring occasionally.

Once the mixture starts boiling, reduce the heat to low to maintain a gentle simmer.

Let the cranberries simmer for about 10-15 minutes or until all the berries have "popped" and become somewhat squishy. The sauce will thicken during this time.

Once the cranberry sauce has reached the desired consistency, remove the pot from the heat.

Allow the sauce to cool down in the pot for a few minutes.

Pour the cooked cranberry sauce into a clean container or jar.

Refrigerate until you're ready to serve.
