1 cup seedless grapes, mix of green and red if possible
1 tablespoon butter
1 tablespoon brown sugar
2 tablespoons cream sherry or port wine
1/4 cup plain yogurt
1/4 cup creme fraiche or Mexican crema or sour cream
Wash the grapes well.
Melt the butter in a small skillet and add the grapes. Add the brown sugar and stir to get it dissolved. Cover and cook over medium-high heat about 2 minutes. The grapes should be beginning to soften and shrivel.
Add the sherry and cook uncovered another 3 minutes or so until the liquid is reduced. Turn off heat.
Combine yogurt and creme and place 2 tablespoons of the mixture along the center of each crepe. Roll up and arrange on serving plates.
