Scrape the salsify and cut into inch long or so pieces and scrub the jereusalem artichokes but do not peel and cut into quarters,
Picture . Put the salsify and artichokes into separate dishes semi covered with olive oil and roast in an oven at 400°F/200°C/Reg6 until golden turning from time to time. This will take between 25 and 35 minutes and the salsify will probably be ready prior to the artichokes. Drain both vegetables on kitchen paper and keep warm
