I prefer the original ensaymada with butter, sugar and cheese but you can absolutely customize this recipe to add your favourite ingredients. For example: - You can top your ensaymada with salted eggs or cream cheese - You can use a triple cheese mixture in your filling and topping - If it's Christmastime, you can even use queso de bola - Ham and cheese would also make for delicious fillings - And I remember eating a grilled ensaymada in the Philippines once; it was fantastic Experiment and make the best version of ensaymada you can!
