One of many versions of the Hungarian vegetable dish. It is often used to compliment meat dishes, and has the texture of a 'thick soup'.
Heat oil in a saucepan, then add paprika and potatoes. Cook, mixing, to thoroughly incorporate.
Add as much water as is needed to submerge potatoes. Add salt, pepper, marjoram, and bay. Simmer until potatoes are tender.
Mix together the sour cream and flour in a small dish. Add some of the juice from the potatoes to temper, then pour the mixture into the pan, stirring to incorporate.
Continue simmering to thicken.
