This morning I had the BEST Roscón de Reyes ever! We bought at Mercadona and it was really good! It made me curious how hard would be to make it from scratch. I found this website that gives excellent step by step instructions with pictures. I hope you like this. Let me know if you ever try this recipe so I can add a comment to this message. I cannot recommend this until I use the steps but it looks really good!
Enjoy it: http://www.yumsugar.com/950218
