Heat the potatoes in the microwave (about 5.5 - 6 minutes at 600W). When cooled, peel and cut into 1-1.5 cm cubes.
In a frying pan, heat butter, sugar, and a teaspoon of water (not listed) over medium heat. Let dissolve without stirring. When the edges start to brown, shake the pan until you get a uniform color.
Add the potatoes. Shake the pan and quickly caramelize the potatoes.
Story Behind this Recipe
I was making these to put into bread dough, and I picked out some to eat as-is and it was unexpectedly delicious (to me ; ). Butter and sugar is also used, but I think it could be a healthy snack.
In Step 1, the potatoes are too hot and soft, so you can't make perfect cubes. So, be sure to cool before working with them. It's okay if the amount of potatoes is a little more or less than the listed amount.
