Does anyone know how to or is there a tutorial for the mini taco cakes as seec here on CC? If so, please email me. Thanks

There are lots of pictures in the gallery of tacos. I would pm someone who has done them before. I am sure they will help you. The one I just looked at looks like it is a piece of fondant colored and folded over. Then I saw a piece of chocolate cake in the center for the hamburger and green colored coconut for the lettuce and white buttercream for the sour cream.
