Sweet Potato Cakes, Tiger Prawns & Ginger-Saffron Yogurt

Sweet Potato CakesRecipe taken from Cook. Nourish. Glow.

I love a sweet potato cake. When I came up with this recipe, I was thinking along the lines of potato croquettes, as they are such a comforting food. Sweet potatoes have a great colour and they are more nutritious than potatoes. This recipe is lovely to have as a treat meal or if you are entertaining, as it’s super easy to make.

Once you’ve got the hang of the sweet potato cakes, have a go at using other combinations of ingredients, like broccoli and spinach, to make a patty with this method, or simply combine potato and fish to make a fishcake.

You’ll need (serves 4)

  • 3 medium-sized sweet potatoes, peeled (approximately 750g)
  • 1 egg
  • 25g coconut flour
  • 3 spring onions, chopped
  • 1tsp sea salt
  • sprinkle of freshly ground black pepper
  • coconut oil, for frying
  • 16 raw tiger prawns, peeled and deveined

For the ginger-saffron yogurt:

  • pinch of saffron threads
  • 125g coconut yogurt
  • 1tsp finely grated fresh ginger
  • 1tbsp extra virgin olive oil
  • squeeze of lemon juice
  • 1tbsp freshly chopped coriander (optional)
  • 1tsp freshly chopped mint (optional)


  1. Steam or boil your sweet potatoes for 10-12 minutes until soft. Drain and dry the potatoes in the pan for 1-2 minutes, then mash them until smooth. Mix in the egg, coconut flour, spring onions, salt and pepper. Form 12 lime-sized balls and press these into patties, about 1cm thick. If making ahead, chill the cakes in the fridge until you are ready to cook them.
  2. Add ½tbsp boiling water to the saffron threads and leave to cool. Remove from the water and mix them into the coconut yoghurt with the ginger, olive oil, salt and pepper. Squeeze in a little lemon juice. You can add coriander and mint as well, if you wish.
  3. Put 2tbsp coconut oil into a large non-stick frying pan over a medium heat. Fry the cakes for 3-4 minutes on each side, until golden brown.
  4. Quickly sauté the prawns in a non-stick pan in a little coconut oil for 2 minutes on each side, until pink and cooked through. Serve the patties with a dollop of ginger-saffron yogurt over the top and the prawns on the side.
