Preheat oven to 375°. Line 12 muffin cups with paper liners.
In a small bowl, stir together grits and ½ cup hot water; let stand for 10 minutes. Strain through a fine-mesh sieve, reserving solids.
In a large bowl, whisk together flour, sugar, baking powder, salt, and baking soda; make a well in center of dry ingredients. In a small bowl, stir together buttermilk, 4 tablespoons melted butter, egg, and strained grits. Stir buttermilk mixture into flour mixture just until moistened (batter will be thick). Spoon batter into prepared muffin cups, filling about three-fourths full.
Bake until a wooden pick inserted in center comes out clean, about 15 minutes. Brush with remaining 2 tablespoons melted butter. Let cool in pans for 5 minutes; serve warm with honey.
