Chop up the onion and sear it on olive oil until crystalized. Cut cabbage to smaller ribbons, rinse it under water.
Chop up garlic and add it to the onion and sear for a minute, then add in the cabbage. Slice up canned tomatoes and add it to the cabbage.
Season with salt, black pepper, celery, paprika powder, cumin and add the bay leaf. (you can also add some sugar to make it a bit sweet)Add 2 dl of water and simmer for up to 40 minutes or until cabbage is soft enough. In the meantime stir and add water little by little when it gets too dry.
Near the end of cooking add cooking cream. Put starch in a cup with some water, stir it and also add to the cabbage and stir until nicely combined. It should thicken it a bit.Taste if needed additional seasoning, serve hot with mash potatoes, polenta or other.
