Peel the shallots and clean the spring onions. Chop both and roast them until golden in melted butter. Add tomato paste, some chili powder, salt and 1/4 l vegetable stock. Simmer for about 10 minutes and then puree. Mix in the rest of the broth, peanut butter and coconut milk with the whisk. Simmer for a few more minutes and season to taste again.
Tip: If necessary, you can also do it without coconut milk or I sometimes use grated coconut for it.
