Vegetables with spices stew in the oil until soft. Add the meat for as little as change its color, then simmer with some water. Add the chopped potatoes and everything boil on slow fire. Once the potatoes are ready, make the mixture for stew (1 pot reaches 1 jar, but with 2 becomes also very nice). Boil for another 10-something minutes and optional add tomato paste or tomato juice. Once the mixture and vegetables for stew tender, remove the pan from the heat, waiting to stop to boil and thicken with flour and water. You can take and fluid directly from the pot to not get lumpy flour. Put salt and leave to simmer for 1-2 minutes.
