Cut potatoes into cubes and soak them in cold water to remove the starch.
Heat cooking oil in a pan and sauté the potatoes until they are golden brown.
When the potatoes are halfway cooked, add onions and carrots and stir-fry together.
Add soy sauce, oligosaccharide syrup, and water, then simmer until the liquid is partly reduced.
Add potato rice cakes and simmer until the seasonings are well absorbed.
Finish with a drizzle of sesame oil and a sprinkle of sesame seeds.
