How To Make Green Bean Purée Soup

Halve the green chili, remove the seeds, and trim the membrane—these hold the most heat. Crush and peel the garlic cloves. Finely dice the chili and garlic, transfer them to a mortar, and add a teaspoon of coarse sea salt. Grind into a smooth paste. Toast the coriander, mustard seeds, and cumin in a hot, dry skillet for 2 minutes. Grind the toasted seeds in the mortar. Heat vegetable oil in a heavy-bottomed pot, add the ground spices and chili-garlic paste, and sauté everything together for 1 minute.

Trim the ends of the green beans and pull off any tough fibrous strings running down the sides. Rinse the prepped beans thoroughly under cold running water.

Scrub the new potatoes or wash them with a stiff brush. Cut larger potatoes into several pieces. Chop the green beans into 3-4 sections.

Pour in 1 liter (about 4 cups) of boiling water. Bring the soup to a boil, reduce the heat to low, and simmer for about 40 minutes—the vegetables need to break down completely until very soft.

To make your Green Bean Purée Soup look like a masterpiece from a fine dining restaurant, pay attention to the finishing touches. Serve it with crispy homemade garlic croutons or a handful of toasted pumpkin seeds to add a lovely textural contrast to the smooth cream. If you are not strictly fasting or eating vegan, a drizzle of heavy cream or a spoonful of grated Parmesan cheese right before serving will make the flavor even richer and more luxurious. Any leftover soup keeps beautifully in the refrigerator for up to two days, and the flavors will become even more balanced. When reheating, add a couple of tablespoons of hot water if the consistency has thickened too much. If you feel like experimenting, try swapping the zucchini for broccoli, or stir in a little coconut milk for an exotic Asian twist. This soup is a wonderful foundation for endless culinary creativity.
