Method
1. Scrub and coarsely grate the sweet potatoes into a bowl. Season with a pinch of sea salt and black pepper. Add the egg, flour, and 1 tablespoon of the mixed seeds. Mix thoroughly until the mixture resembles a cross between a dough and a batter. Divide into four portions and roll each into a ball.
2. Preheat an electric sandwich or waffle maker. Once hot, grate a little Cheddar cheese into each compartment, place a sweet potato ball on top, and press down evenly with a spatula. Grate more cheese on top, close the maker, and cook for 8 to 10 minutes until golden and crisp. Keep warm in a low oven and repeat with the remaining mixture.
3. For the salad, drizzle 1 tablespoon of extra virgin olive oil into a serving bowl, add 2 teaspoons of red wine vinegar, and season with salt and pepper. Score the cucumber lengthwise with a fork, then thinly slice and add to the bowl. Chop the little gem lettuces an inch from the bottom, separate the leaves, finely slice the stalks, and add to the bowl. Toss just before serving.
4. To serve, top each rosti with a dollop of cottage cheese, a sprinkle of mixed seeds, and a dash of chilli sauce if desired. Toss the salad leaves in the dressing, scatter over the remaining seeds, and serve alongside the rostis.
Alternative Cooking Method
If you don’t have a sandwich or waffle maker, heat 1 tablespoon of olive oil in a frying pan over medium-low heat. Flatten each sweet potato ball into a patty and cook for 3 to 4 minutes on each side until golden and crisp. Push the patties to one side, grate some Cheddar cheese directly into the pan, place the rostis on top, and cook for another 2 minutes until the cheese is golden brown.
Tip
You can batch-cook the rostis and freeze them. To reheat, place in a hot oven for 15-20 minutes until cooked through and crisp.

Cook techniques
Grating Sweet Potatoes
Scrub the sweet potatoes thoroughly before grating to remove any dirt. Coarsely grate them for better texture, which helps to create a crispy exterior when cooked.
Mixing Ingredients
Combine grated sweet potatoes with egg, flour, and mixed seeds in a bowl. Ensure that the mixture is well-blended to create a consistent dough-like texture, making it easier to shape into balls.
Using a Sandwich or Waffle Maker
Preheat the appliance according to the manufacturer’s instructions. Use a spatula to press the sweet potato balls evenly to ensure even cooking and a golden crisp.
Cooking in a Frying Pan

Preparing a Salad
Create a fresh salad by mixing olive oil with red wine vinegar and seasoning. Score the cucumber lengthwise for a decorative touch and enhance the salad with chopped little gem lettuce.
