Jerusalem artichoke soup
Crema di topinambur
Jerusalem artichokes are not from Jerusalem, and they are not artichokes. They are a species of sunflower native to North America with elongated, uneven tubers that can be used as root vegetables. The consistency and raw texture is similar to potatoes, but Jerusalem artichokes have a sweeter, nutty flavor that works well with apples and in salads.
Boiled they tend to become soft and mushy, which is why they make such brilliant soup material as proved by this Jerusalem artichoke soup.
