• Remember you want this to be white so no green stuff!
  • Sweat the onions in a big knob of butter with salt and pepper until nice and soft.
  • Add all the other vegetables and sweat for another 10 minutes, being very careful not to brown them.
  • Add the stock and simmer until everything is soft.
  • Liquidise and then if you want it extra smooth, sieve in a fine sieve, this is really worth it.
  • Finally, add cream and adjust seasoning.
  • Tip - We highly recommend the sieving bit, taste it before and after, you'll be amazed by the difference.
  • Also, don't worry if it's not really white after whizzing. The cream will sort this out!
