Scott Wilson of the blog Taco Matrix has written a book about Tacos. It’s a great recipe book with recipes for everything from how to make a taco de lengua (tongue taco) to carne asada to duck breast taco. It also has some great salsa recipes. The photos are professionally done by Lara Ferroni Photography.
I think an interesting contest would be to have a photo contest for the best photo of a taco or tacos. The winner of the contest gets a copy of Tacos: Authentic, Festive, and Flavorful.
