Peel and dice the onion, garlic and potatoes. Heat some oil in a saucepan and sweat the diced vegetables and corn in it. Add the stock, a little salt, pepper and chilli flakes and fill up with water. Simmer until the potatoes are tender. Puree the soup vigorously. Possibly pass through a sieve again if you don`t like the corn husks. Add the cream, bring to the boil and season with salt, pepper, the chilli and a splash of lemon juice to taste spicy and hot.
Cut hearts out of the bread slices with a cookie cutter. Roast the breads in a little salted butter in a pan and serve with the soup.
