At the temple to dairy produce that is Granja Viader (Xuclà, 4-6), the lactose-intolerant may not be able to partake of a suís (hot chocolate topped with whipped cream), but they can sample the thick, Spanish-style hot chocolate, made only with water, cocoa, chocolate and cinnamon. It also has plenty of coeliac-friendly edibiles: their home-made chocolates, sponge fingers, cheesecakes, 'crema catalana' and creme caramels are 100-percent gluten-free. At Syngluten (Galileu, 115) they make delicious gluten-free 'churros con chocolate' – you can get them lactose-free too.
There’s only one Barcelona bakery exclusively dedicated to gluten-free bread: Celiadictos (La Pobla de Lillet, 5. T. 93 409 31 31), which also covers dairy intolerances, as none of their breads contain milk. Isabel Trullenque says that their products have nothing to do with cheap ersatz breads made from cornmeal. Instead, by blending flours made from gluten-free grains – eg, quinoa and buckwheat – they make traditional country loaves, baguettes and sliced loaves that are tasty in their own right. They’re not cheap: the quinoa loaf costs €13 a kilo, thanks to international futures markets.
