Cut a cross in the bottom of the tomatoes and poach them for 2 minutes. Take off the tomatoes skin and cut them in 4 pieces. Put them in the COMBEKK Dutch Oven to boil for 15 minutes. Stick mix the tomatoes until you have a smooth soup, add salt and pepper to your taste. The secret of a perfect tomato soup is blending it until the soup is very smooth. Use a good stick mixer and blend it well for at least 5 minutes.
