  1. Preheat the oven to 220C/Gas 7/fan oven 200C. Combine all the spices and salt in a small, electric spice or coffee grinder (or use a pestle and mortar), and pulverise them to a powder – ignore the bigger bits of coriander husk. Tip the ground spices into a very large mixing bowl.

  2. Cut the onions into sixths, leaving a little root attached to hold the layers together. Cut the ordinary potatoes into six segments, lengthways. If the sweet potatoes are slender (they normally are) cut them into quarters, lengthways; if they’re bulky round the middle, cut them into sixths. Put all the vegetables into the mixing bowl, add the oil and toss thoroughly, using clean hands

  3. Lightly oil the large tray which comes with your oven (or 1 or 2 baking trays), spread the vegetables out in a single layer and bake them for 25 minutes. Meanwhile, combine the glaze ingredients in a small jug with 4 tablespoons cold water. Remove the oven tray, brush the vegetables with the glaze and continue to bake for about 20-30 minutes, or until they’re slightly charred and tender. A little squeeze of lime or lemon juice adds vivacity, but the vegetables are very nice with or without it.

Delicious - this has become a firm favourite in our house. I sometimes use parsnips if I can't get sweet potatoes; works nicely too.

I made this with Peking Duck and it was delicious. The pepper makes it quite hot but it was an interesting taste

I made this with crispy chicken bites and my family loved it. It's a brilliant recipe, but I left out the coriander.
