My Austrian friend Hermine taught me this recipe. I'm afraid there are no quantities ... just use enough onions and potatoes to produce the amount of food you need, and use enough paprika to make it as spicy (or un-spicy) as you like.
potatoes (cut into 1 cm cubes)
onions (finely diced)
paprika (hot or sweet, as you prefer)
salt (to taste)
Cook the onions in oil until golden. Add paprika and a little hot water to the onions, then add the potatoes and stir until potatoes are coloured by the paprika. Add a little salt if you wish. Cover with boiling water, add a bay leaf, and simmer for about half an hour. Enjoy.
