"Editor's note: Chef, nutritionist, and cooking teacher Lourdes Castro shared this recipe from her cookbook, Latin Grilling. It's part of a festive Cuban party menu she created for Epicurious. This dish gets its name from the wars between the dark-skinned Moors (moros) and the lightskinned Spaniards (cristianos) that occurred during the eighth century in Spain.
