Clean and wash the leek and cut into fine rings. Wash the corncobs and cut the grains. Cut bacon into fine strips
Heat the oil in a pot. Leave the bacon in it until crispy. Take out. Sauté leek in hot bacon fat, remove half. Add the lentils. Stir in a good 3/4 l water, bring to the boil. Add corn grains and simmer covered for about 25 minutes.
Lift out 2 tablespoons of corn. Puree the soup finely with the cutting stick and if necessary pass through a fine sieve. Stir in broth and cream. Season to taste with salt, pepper, Tabasco and vinegar. Serve the soup with leftover bacon, leek and corn. Garnish with parsley
Unless you want to buy extra red lenses: cook soup only with corn and possibly with a larger stick of leek
