Prepare the cabbage: wash, remove outer wilted leaves, remove stem and core
Cut the cabbage into about 1cm strips
Cut the potatoes into cubes into 2 cm (¾"), mince the garlic
Place the savoy cabbage strips, potatoes, garlic, turmeric, marjoram, caraway seeds, salt, pepper into a large pot, and add the water
Bring it to boil, then let it simmer covered for about 30 minutes, until the potatoes and the savoy cabbage are tender.
In the meantime prepare the roux: heat the oil in a small pot on medium heat, add the flour. Lower the heat and keep stirring it for a few minutes until the oil flour mix is getting bubbly and gets a whiter colour. Remove the roux from the heat, add the sweet paprika, and mix it together.
Add the roux to the cabbage potato mix, stir it, and cook the stew for another 3-4 minutes until it thickens.
