Pumpkin "Olga"

French pumpkin soup.
Cook this soup for several days at once, because over time the dish infuses and becomes even tastier.
You will need: 0.5 kg of pumpkin, 3 potatoes, 1 onion, 70 g of celery root, 1.5 cups of milk, 0.5 tsp. dried ginger, spices, 150 g white bread croutons.
Preparation: Lightly fry the diced vegetables in vegetable oil, pour boiling water over it so that it slightly covers the contents of the saucepan. When the vegetables become soft, drain the broth, puree the products with a blender, pouring in warm milk to achieve the desired density. Boil the puree soup for 8 minutes over low heat, add spices.
