What each ingredient does
- Cardoons
- Provide the main body and flavour of the puree once cooked and sieved.
The step that matters
Boil the sealed cans in a hot water bath. The cans must be held at a sustained boil for the full time so the contents are heated thoroughly and the seal stays intact during preserving. Shortening the time or letting the water drop below a boil risks spoilage.
