Chop the leek, garlic and chili peppers and add to a food processor.
Add in sweetcorn, flour, lime, olive oil, salt and pepper.
Pulse the food processor to make a sticky batter that's well incorporated. You can do this in batches if your food processor is too small.
Let sit for 5 minutes.
With slightly damp hands, take some of the batter and form a pancake (aiming for around the size of the palm of your hand)
Add the fritters to a pre-heated, non-stick frying pan and fry on each side for around 5 minutes. You can add a little bit of oil to the pan if you'd like it to be more crispy, but do cook them on a lower heat if that's the case.
Mix mayonnaise and lime together to make a dip. Optional: add a pinch or two of chili powder if you want a kick in your dip!
