I'm very fond of experiencing different recipes.So,here's the result today
by using what I found in my fridge:chestnuts,fennel,arugula,unsweetened condensed milk.
Cook on moderate heat:1 garlic clove, 1 fennel bulb cut in pieces for 5 minutes.Add the jar of peeled chesnuts,vegetable broth,pepper and cook for another 15 min.Wait a few minutes till the soup cools down.Add some fresh arugula.Then blend the soup,adding 1/4 cup of condensed unsweetened milk.Serve with a pinch of "piment d'espelette".
