Blue corn and cheese quesadillas recipe
 These tortilla turnovers filled with cheese come from Xochimilco market, 20 miles or so from the centre of Mexico City. These quesadillas are made from blue corn and ooze with melted cheese and wilted courgette flowers. When courgette flowers are out of season, use Swiss chard or spinach. 250g/9oz blue corn tortilla flour (or maize flour if unavailable)2 tbsp olive oil1 onion, finely sliced1 green jalapeño chilli, finely chopped or a good pinch dried chilli flakes1 garlic clove, finely chopped250g/9oz courgette flowers, Swiss chard or spinach, washed and shredded200g/7oz mozzarella, grated 150g/5½oz Lancashire cheese, crumbledsalt 250g/9oz blue corn tortilla flour (or maize flour if unavailable) 2 tbsp olive oil 1 onion, finely sliced 1 green jalapeño chilli, finely chopped or a good pinch dried chilli flakes 1 garlic clove, finely chopped 250g/9oz courgette flowers, Swiss chard or spinach, washed and shredded 200g/7oz mozzarella, grated 150g/5½oz Lancashire cheese, crumbled salt Method Place the flour in a large bowl with ½ teaspoon salt and add 275ml/9¾fl oz lukewarm water.
