1 tablespoon melted butter
2 cups flour
1/4 cup sugar
1 teaspoon kosher salt
1 teaspoon baking powder
1/2 teaspoon baking soda
1 egg
1 1/4 cups sour cream
1 tablespoon lime juice
zest of two oranges
2 peaches, peeled, pitted, chopped

Preheat the oven to 400 degrees F and grease or paper 12 muffin tins.

Mix dry ingredients together. Beat egg with the sour cream, melted butter, lime juice, and orange zest. Pour the wet ingredients into the dry ingredients and stir/fold gently until just combined. Fold in the peaches.

Pour into prepared pan. Bake for 20-25 minutes until a toothpick comes out clean when inserted.
