Preheat oven to 350ºF. Line a muffin pan with paper liners.
Toss cranberries in one tablespoon of the flour in a medium bowl to keep them from sinking to the bottom of the muffins while baking. Mix the rest of the flour with the baking soda and salt in a separate bowl and set aside.
2 cups (282g) all-purpose flour, 3/4 teaspoon baking soda, 2 cups cranberries, 1/4 teaspoon salt
In a mixing bowl, whisk eggs, oil, and sugar together, then add sour cream, orange juice concentrate, water, and vanilla extract.
2 eggs, 1/2 cup vegetable oil, 3/4 cup granulated sugar, 1/3 cup sour cream, 1/3 cup orange juice concentrate, 1/4 cup water, 1 teaspoon vanilla extract
Stir in dry ingredients by hand until just mixed. Gently stir in cranberries and orange zest.
1 Tablespoon orange zest
Divide between 14 paper-lined muffin cups. Sprinkle with sugar. Bake in center of oven for 16-18 minutes, until muffins are beginning to brown on top. You likely wont’ be able to use the toothpick test because of the cranberry juice, but the tops should spring back when you bounce a finger on them.
1/4 cup sugar
Remove from oven, and let cool on a wire rack.
