I believe Hampshire produces the most; tho' they are found in Windsor-park, and several other counties of England. They are imported from abroad, and fold at a very high price in most Italian shops; but their flavour is much wasted, and very little superior to those found in England. They grow in the ground without any outward appearance. The Author says, that, as Pigs are very fond of them, and have often been the occasion of discovering where they grow, the hint might be useful in England, were a little more attention paid to it.

See Artichokes, ditto, Truffles either boiled or baked will do for this purpose, though they have been before served at Table.
