Sauté the onion until golden brown, add the carrot and sauté. When the vegetables are soft, add the water, preferably lukewarm (you can use vegetable stock, but it is not necessary).
Cook for 15 minutes, let it cool and blend until you obtain a cream without lumps.
Add the orange juice and the vegetable drink, season with salt and pepper, stir well and serve with a splash of Modena vinegar and a couple of basil leaves.
