Directions

1. Mix the wet ingredients (butter through eggs) together.

2. In a separate bowl, mix the dry ingredients (flour through baking soda, skipping the masa).

3. Divide the dry ingredients equally into two bowls, and add the yellow masa to one and the blue to the other, mixing until incorporated.

4. Add half of the wet mixture to each bowl, mixing until no lumps remain.

5. Set your Ooni to the lowest setting and preheat for 30 minutes with a 12 inch cast iron skillet inside. If you're using an oven, preheat with the pan inside at 425 degrees.

6. After 30 minutes, remove the skillet and add a tablespoon of butter, swirling to coat the surface.

7. Pour 1/4 of the total quantity of the yellow batter into the skillet, then 1/4 of the blue, repeating with alternating colors until the batter is done. Drag a chopstick or toothpick in straight lines from the top to the bottom of the skillet, working from left to right, to create a marbled effect.

8. Ooni instructions: Bake for 15-20 minutes, rotating the pan 180 degrees after 10 minutes to avoid browning more on one side.

9. Oven instructions: Bake for 20-25 minutes.

10. Check for doneness by moving the pan — if the dough stops jiggling, it is done. Allow to cool for at least 5 minutes before slicing into wedges or squares.
