These are really good. Never thought to add grapes to a muffin batter. It's a great marriage.

Grape Muffins

Whisk together and set aside:
1 1/2 cups flour
1 1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt

Beat together until light and fluffy:
1 stick butter, softened
2/3 cup sugar
Add:
2 large eggs
1 tablespoon orange zest

Add flour/wine alternately to butter/egg mixture in two batches beginning and ending w/flour:
2/3 cup wine (sweet/dry) I prefer a sweet wine.

Fold in:
1 cup seedless red grapes tossed with an additional 1 tbsp flour into finished batter.

Divide batter among 12 muffin cups with liners or sprayed. (I only make 11 and fill extra muffin space with water before baking.) Bake 350 oven until golden and springy to the touch for approximately 18-20 minutes. Cool in pan 5 minutes. Remove and dust w/confectioners' sugar before serving.
