Unlike most tamal recipes, which use dried corn (masa harina), this one is Cuban-style, made with fresh corn kernels. I've also added a different touch by replacing the traditional pork filling with conch. The flavor and texture proved very popular at Yuca, and it remained on the menu as a fixture.
These tamales are very convenient for entertaining. They can be made ahead of time and frozen, or kept in the refrigerator and then popped in the microwave. In fact, it's not worth making a smaller batch, so you'll probably want to freeze some of them. Likewise, the pesto can be prepared ahead of time and refrigerated.
