This sounds like something your kids made up, doesn't it? They almost could have.
3 cups strawberries
1/4 cup granulated sugar
3 cups water
1 strip lemon zest, (yellow part only)
1 cinnamon stick
1 tbsp cornstarch
2 tbsp cold water
1 cup sour cream, (regular or light)
Wash and hull the strawberries and cut them in quarters. Helpful children can be a greater asset here. (A few bonus berries might be provided as added incentive.) Dump the strawberries into a medium saucepan and combine them with the sugar, water, strip of lemon peel and cinnamon stick, if you're using it. Bring to a boil, and simmer for 10 minutes.
In a little bowl, mix together the cornstarch with the 2 tbsp. (30 mL) cold water and gradually add to soup. Boil 5 minutes longer, until just very slightly thickened. Remove from heat. Chill for several hours. Just before serving, stir a few spoons of the soup into the sour cream to thin it, then add it to the soup, mixing until smooth.
Ladle the soup into bowls, then have your helper float a small island of sour cream on each serving, topped by a single, perfect (or not perfect) stranded strawberry.
