Super tasty!!!

I made this with rather peculiar stock - the coca cola that I had cooked a gammon joint in, but the robust flavour stood up well to the roasted parsnip (+ carrots, + swede) with the spices. The resulting soup is delicious.

I've made this soup twice now. I use slightly more onion that it states and add a dash of cream at the end to give a little more richness. So simple and a great way to use up slightly less than perfect veg. Have also made with sweet potatoes too & was excellent also

Excellent. Substituted a parsnip for carrot for more variety and I was very generous with the spices. Ground them in pestle and mortar before mixing with oil. Didn't use the tomatoes and it was still lovely!

Love this recipe! I don't use coriander seeds or tomatoes and I put in wholegrain mustard instead of mustard seeds (just using what I have in..) but it's great regardless. It's becoming a regular of mine!

OOOH! This is yummy - didn't quite have the weight of parsnips so made it up with a couple of carrots. Lovely subtle spiced flavour and very easy!

It was delicious, I pushed it through a strainer, which I thought made it look better, plus I wasn't a fan of the whole seed texture. However I do think it was important to use the spices whole, which gave it a much more subtle flavour rather than a full on curry hit.

I made this yesterday for the first time. Taking in to account previous comments I doubled the 4 main spices, I added a red chilli with seeds and a sweet red pepper. It was quite hot but delicious. I might put half a chilli next time. I did grind the seeds as I dont like gritty bits. Will definitely be making it again :)

Just cooked this recipe for the first time in years, it's still amazing! The seeds didn't bother me at all, my blender crushed them up nicely. Beautiful flavours, and I'm not even a parsnip lover. I was a bit more generous with the spices than the recipe states, plus I added some nigella seeds that I had in the cupboard. Delish.
