Picking Parsnips Too Early

This year for the first time in a very long time I've managed to coax parsnip seeds into life. I'm not sure exactly, why parsnips haven't germinated before but I took the advice of Charles Dowding's you tube video on germinating all seeds in a modular tray. Sure enough and with moisture from a capillary mat, they germinated very well and so we're planted out and we'll watered and fed. In August I noticed the white body perming through the earth and couldn't resist pulling up...just one. This one was big...though you can see that the root part is quite narrow and needed more filling out. Tasted delicious,though, baked in the oven, sliced and oiled into mouth sized chunks. Extremely filling as a vegetable. I know this vegetable is best appreciated when left to be pulled after the first frosts or even later, when some of starch turns into sugar. I've left the rest, hoping for feast in November. ..if I can wait that long!
