How to Make It
Preheat oven to 350°F with rack in middle of oven. Grease a 12-cup muffin pan with cooking spray. Brush muffin cups with 2 tablespoons tahini.
Whisk together semolina flour, sugar, gluten-free flour, turmeric, baking powder, and salt in a large bowl until combined.
Stir together ghee and remaining 2 tablespoons tahini in a small bowl until combined. Add tahini mixture to flour mixture, and stir just to incorporate. Slowly whisk in 3/4 cup water until a smooth batter forms. Spoon batter evenly into prepared muffin cups. Sprinkle evenly with sesame seeds.
Bake in preheated oven until set, about 25 minutes. Increase oven temperature to broil, and broil until muffins are golden brown, about 2 minutes. Let muffins cool in pan on a wire rack 10 minutes. Remove from pan, and serve warm or at room temperature.
