1/3 cup superfine sugar
juice of one meyer lemon, a regular lemon or other citrus (about 1/4 cup)
Combine the cream and sugar in a small saucepan. Bring just to a simmer over medium low heat and remove from heat. Let stand until just cool, stirring occasionally, about 20 minutes.
Stir in the lemon juice. Blend well. Divide between 2 goblets or small serving dishes, cover and chill until firm, at least 4 hours and preferably overnight. Garnish with fresh blueberries, if desired, before serving. Recipe may be doubled, tripled, etc with no problem
