sliced fresh strawberries for garnish
Mix the crushed strawberries, orange juice, sugar, and one cup of water together in a saucepan. Simmer, stirring often until the sugar dissolves.
Mix together the potato starch with 1/4 cup cold water and then add the mixture to the soup. Cook, stirring until the soup thickens, about 2 minutes.
Chill the soup. Serve garnished with strawberry slices.
