You may think of prawn cocktail as a kitch '70s dish, but in Mexico it is half Bloody Mary and half seafood starter. Tommi whips up her version, complete with a generous helping of tequila; and possibly the most delicious dessert in the world, churros - crisp, warm doughnuts dipped in a rich, melting chocolate sauce. Plus, having visited the main meat market in Oaxaca, Tommi is inspired to create a hot chorizo and squash salad, before trying to pick up a partner at the Danzon, a weekly street dance in Mexico City where the locals strut their stuff in their best ballroom outfits.
