These would be SO easy and quick if you have a food processor with a grating attachment. But I don't. Still easy but the veg prep is a bit time-consuming.
I served them with a garlicky blue cheese dip. Made with teaspoonfuls of batter, they'd make a really excellent nibble for a drinks party and the recipe is easy enough to size down if you aren't batch-cooking for a week's meals. I deep-fried but I can't really see them coming to any harm if you shallow fry. Just make sure they are set quite firmly before you try to flip them.
Sweet potato and corn fritters (makes about 20)
3 sweet potatoes, peeled and coarsely grated
4 cobs of corn, kernels sliced off
1 onion, finely sliced
2 leeks, finely sliced
1 green pepper, chopped
small bunch of coriander, chopped
3 large eggs
2 cups self-raising flour, approx
salt, pepper and smoked paprika
Mix all the veg in a large bowl with the eggs and season with salt, pepper and a little smoked paprika, then add flour until it forms a pretty thick batter.
Heat 2" of oil in a deep saucepan to 180C, then press handfuls of the batter into balls and carefully drop into the oil. Cook for about 4 minutes on each side, in batches, draining well on kitchen paper.
