Now you may buy a lot of broccoli or at least weekly and be in the habit of cutting the chunky stalk out and throwing it away. Don't do that, save your stalks in the freezer then use in the soup instead of using all the good florets. Chop them up and use in place of the broccoli in the recipe. When you have puréed the soup with a blender then pass the soup through chinois (conical strainer). This will remove the tough fibres that don't break down in the cooking process.
