and the leek that you have washed and finely cut, let it dry all over low heat. Then add the potatoes and carrots
and the two sprigs of rosemary and let them jump a few minutes to flavor them. Then add the broth and continue cooking. When the vegetables are cooked (it will take about 40 minutes), remove the two sprigs of rosemary and blend them finely in a mixer to obtain a creamy consistency, if the cream is too thick add a ladle of hot water.
Finally season with salt. Serve the purple carrot cream hot or warm, accompanying it with a spoonful of sour cream or low-fat yogurt!
