Be sure to buy the reddest and ripest strawberries you can find for best flavor. Rinse strawberries, then cut big ones into fourths and smaller ones into halves. Put cut strawberries into a medium-sized bowl. In a small bowl, whisk together the sour cream and sweetener, brown sugar, or a combination of the two. Taste for sweetness to see if you want to add more sweetener. Gently combine sour cream mixture with cut strawberries, divide into four small dishes, and serve.
