CHAP. 28.—THE SKIRRET.
The skirret,[1013] too, has had its reputation established by the Emperor Tiberius, who demanded a supply of it every year from Germany. It is at Gelduba,[1014] a fortress situate on the banks of the Rhenus, that the finest are grown; from which it would appear that they thrive best in a cold climate. There is a string running through the whole length of the skirret, and which is drawn out after it is boiled; but still, for all this, a considerable proportion of its natural pungency is retained; indeed, when modified by the addition of honied wine, this is even thought to impart to dishes an additional relish. The larger parsnip has also a similar sting inside, but only when it is a year old. The proper time for sowing the skirret is in the months of February, March, April, August, September, and October.
