If any of your carrots, parsnips or turnips are particularly big, chop them in 1/2. You can parboil the carrots, fennel, parsnips, and baby turnips together-everything except the beets, as they'll turn everything else red! The beets also take quite a bit longer to cook, around 20 to 25 minutes.
Put the rest of the vegetables into a large pot, cover with cold water and season well. Bring to the boil and cook for about 6 to 7 minutes until you've got part-cooked, softened bendy vegetables, and then drain in a colander and leave to steam dry.
Get yourself a small tray, and use it to mix up each set of vegetables with their own gorgeous flavours, a few good lugs of oil and a good pinch of salt and pepper. Toss the carrots, clementines and rosemary together first and move them to a larger roasting tray so they're all together.
Then mix your fennel with its flavours and do the same... When you get to the parsnips, keep the honey back for later. Make sure each vegetable group is separate in the roasting tray. Cover the tray with tin foil and keep in the refrigerator or the garage until your turkey is out of the oven and resting.
When you are ready to cook them, preheat your oven to 375 degrees F/ 190 degrees C/ Gas 5. Roast the vegetables in the hot oven for 50 minutes to 1 hour until they are golden, crispy and beautiful looking. Five minutes before they are ready to come out of the oven take the tray out, drizzle the honey over the parsnips and jiggle the tray so they are nicely coated.
Pile all the vegetables up on a platter so they sprawl and hang all over the place. That platter is like winter in a nutshell, and every single mouthful will taste different and exciting - you'll definitely want to keep it close to you at the table.
