Wash the carrots, cut them on the bias into slices (medium thickness).
Chop the onion and finely dice the celery stalk.
Steam the carrots for about 10 minutes. They should be barely tender.
Meanwhile, heat a little oil in a frying pan. Brown the onion, stirring occasionally. After 5 minutes, add the celery. Continue to stir and fry for a further 5 minutes. The onion should be tender and translucent.
Then add the carrots to the pan. Fry for 2/3 minutes and add the white wine. Let the wine evaporate and the vegetables simmer for 5 minutes on low heat.
 After that,  pour in the tomatoes (diced beforehand). Add the flour and stir to mix it well with the tomato juice.
Add the bay leaf, thyme and rosemary and simmer for 30-40 minutes on low heat, stirring occasionally.
Meanwhile, prepare the gremolata. Rinse and dry the parsley. Chop it finely. Finely chop the garlic. Remove the lemon or orange peel (organic). Mix everything together in a bowl and sprinkle with a tablespoon of lemon or orange juice.
 Add the mixture to the vegetables 5 minutes before stopping the cooking. Your dish is ready!
