Step 1Heat oven to 425 degrees. Combine the flour, semolina, baking powder, salt and pepper in a mixing bowl and stir with a fork until well mixed.
Step 2Add the cheese, chorizo, green onions and corn. Toss to combine. Stir in the melted butter, eggs and half-and-half and mix well.
Step 3Brush 4 madeleine tins generously with melted butter. Spoon the batter in to fill each mold about halfway. Bake until tops are puffed and set and bottoms are well browned, about 12 minutes.
Step 4Cool slightly, then unmold. Serve warm.
