Empanadas and Passion-Fruit Jellies

Not a lot of people know that empanadas originally came from Cornwall, inspired by the humble pasty - a favourite dish of the tin miners who came to work in Mexico in the 19th century. Thomasina's hunt for the best empanadas in the country takes her to the Oaxacan valleys and a small village called Ocotlan, where a lady called Carmelita whips them up in her backyard. Plus Tommi shares the recipe for her all-time favourite spicy crab noodles, and an exotic and zesty passion-fruit jelly.
