These sweet potato cakes are dead easy to make, and perfect for brunch or supper. You could also make smaller cakes and serve them as a snack with some salsa or chutney. We had them for brunch with a poached egg on top and a fresh, crunchy salad. To keep it vegan, serve a sliced avocado or a good dollop of coconut yoghurt alongside the potato cakes instead of the egg. This is a very useful recipe when you have left-over roasted or boiled sweet potato – sometimes you can only get enormous ones, which are far too big to get through all at once.
The potato cakes are very soft – you could use more cornflour and chill them for longer if you want firmer, neater patties – but I don’t mind them being a bit wonky, and they held together fine in the pan. Adjust the chilli content to your taste, and chilli flakes would work too if you don’t have any fresh chilli. You could, of course, omit the ginger and chilli and use parsley and lemon zest instead of coriander and lime zest if you wanted a milder, more soothing brunch. Serves 2.
1 large sweet potato (about 300g)
2 spring onions
1 clove garlic
1 red or green chilli
zest of 1/2 lime
6 sprigs coriander
1 tbsp cornflour
salt and black pepper
2 tbsps quick-cook polenta
1 tbsp olive oil
1 stick celery
juice of 1/2 lime
2 tbsp olive oil
To serve (optional):
2 eggs or 100g coconut yoghurt
Bring a pan of salted water to the boil. Peel the sweet potato and cut into small chunks. Add to the boiling water and simmer for 10 minutes until tender to a fork, then drain thoroughly in a colander.
Trim and finely chop the spring onions, peel and grate the ginger and garlic, de-seed and finely chop the chilli and put into a bowl with the zest of lime. Finely chop the coriander, including any soft stalks, and add that too. Tip the drained sweet potatoes into the bowl and mash them into the other ingredients.
Add the tablespoon of cornflour and mix well. Then spread the polenta onto a plate. Take a quarter of the mixture, shape into a pattie and dump on top of the polenta. Carefully turn it over (using a spatula helps) so that it is completely coated in the polenta.
Move the potato cake onto a plate or board and do the same with the rest of the mixture to give four sweet potato cakes. Pop them into the fridge to firm up for a few minutes while you clear the decks, make salad and lay the table.
For our salad we just diced the vegetables listed and dressed them with lime juice and olive oil. Diced red pepper or red onion would also be nice, as well as or instead of the ones listed. Or you could just prepare a regular green salad.
Heat the oil in a non-stick frying pan. If you’re having poached eggs put a shallow pan of water on to heat.
When the oil is hot use a spatula to transfer the potato cakes into the pan and leave to cook undisturbed – resist the urge to fiddle with them – on a medium heat for 5-7 minutes until the bottom is crisp and golden. Turn them over carefully with the spatula and cook the other side.
Slice the avocado, if having, and squeeze over a few drops of lemon or lime juice to stop it discolouring. If you’re having poached eggs, about 3 minutes before the potato cakes are ready crack each one into a cup and slip into just simmering water. Cook for 3 minutes or until done to your taste. Use a slotted spoon to scoop each one from the water and blot any excess moisture with a kitchen towel.
Serve the potato cakes with their sides and salad for a satisfying, spicy brunch.
