Sift the flour and baking powder into a bowl, making a well in the centre.
Add the eggs, half the milk.
Beat until smooth, then gradually whisk in the remaining milk.
Fold in the corn, spring onions, chilli, lime juice, feta and herbs.
Heat and lightly oil a heavy-based frying pan.
Drop 2-3 heaped tablespoon of the mixture into the pan and fry over a medium heat until golden brown and cooked through.
Transfer to the oven to keep warm.
