- Preheat the oven to 200ºC/400ºF/gas 6. Scrub the carrots, then cook in a pan of fast-boiling salted water for 10 minutes, or until just tender, then drain. Finely grate half the orange zest into the empty pan and squeeze in all the juice. Place on a medium heat, add the bay, thyme and a good pinch of sea salt, then cook until syrupy, folding the carrots back into the glaze to coat. Leave to cool.
- One by one, lay out the filo sheets, rub with oil, then cut lengthways into 3 strips. Place a carrot at the bottom of each and roll up like a cigar, squeezing lightly to seal (don’t worry about being too neat). Repeat with the remaining carrots and filo, placing them on a baking tray as you go. Brush each lightly with oil, then roast for 20 minutes, or until lightly golden and crisp, drizzling with a little honey and scattering with the sesame seeds for the last 5 minutes.
- Stack the carrots on a board, scattering over any sesame seeds left on the tray, then swirl the tahini and harissa through the yoghurt and serve alongside.
People love this as a nibble, starter or side, and are always surprised if you use different coloured heritage carrots – pink, purple, yellow . . . whatever you like!
