I read the previous comments and made this with coconut milk instead of cow's milk. I also used a pouch of preprepared puy lentils instead of the red lentils. I have to say that this is the best soup I have ever made, maybe even ever tasted! Went down well with all members of the family.

I made this last night, absolutely scrumptious. I used madras curry paste and didn´t bother to grate everything as I knew I was going to whizz it all up. Will definately be making this again. I´ve even got some in the fridge at work to have for lunch.

love this recipe, chop up, chuck in, cook eat yum yum.

I have just discovered tandoori curry powder and it made this soup utterly amazing. Tandoori curry powder has a slight sweet chilli flavouring and would make a fabulous dhansak.

Very nice. I thought it tasted a bit like a sweet curry. Not sure if that was due to me using mild indian curry paste rather than curry powder. Might use more than one lime in future to cut the sweetness a bit.

Fantastic recipe, just what you to warm you up on a cold day. Used soya milk to make it dairy free.

Do not grate the ingredients it is absolutely not necessary. Very tasty soup, quite sweet but then it is made with sweet potatoes. Will be making again.

Made this soup last night, first soup I have made and it tastes delish. I grated everything too without reading other comments and it was the biggest pain! Will definitely just cut up next time

Just made a batch and it's amazing , also started grating and halfway gave it up and chopped. Also added in some more curry extra kick ....may add in prawns next time when cooking the curry ,then remove and add in just before the end ...will see and report back ...

Fantastic soup for a cold day (like today), also very tasty without adding a lime juice. I have not blended my soup (as I prefer to taste the vegetables), but made sure that I cut sweet potatoes into small chunks, cut onion into fine pieces and grated apples. All with very good results.

I chop the following vegetables to taste:


And on:e breast (or leg) of chicken

Boil for 15 min. then add lentils and boil for a further 15 min. Add some single cream and frozen peas.

Remove chicken and blend everything else, then add the cut-up chicken. Soup consistancy to taste.

Eat with thick slices of granary bread.

This is a complete meal !!

Like others, grated only the ginger. I also used 150ml coconut milk and 150ml skinny milk instead of the 300ml milk only. I think it works superbly. Gorgeous. In fact, I'd go so far as to say that, produced with the coconut milk, this is one of the best soups I've had.

This was quite good. I didn't have curry powder on hand, so I substituted the curry powder for garam masala and amchor. Also, having made this with both cow and coconut milk, I must say, coconut milk gives the soup a wonderful complexity that I find is missing when using cow's milk.

Lovely soup! I normally manage to mess soups up but this was so easy once I'd finished grating! I think next time I'll add a bit of chilli to give it an extra kick

georgous soup will make again. just the thing for a cold winters night.

Made this for my lunch for the week, wasn't sure at first but it grew on me as the week went on, now I'd make it again. Replaced some of the sweet potato with 2 carrots and didn't add the milk, I also only blended half because I like my soup a bit chunky. Was yummy as the cold weather was setting in

Just made this, super tasty. As I already had some baked sweet potatoes I used these instead of grated raw ones, and so only used 600ml of stock. I also didn't have any milk so I used 100ml of slightly sweetened soya milk. Delicious!

Delicious! Chopped instead of grating, used ground ginger and ground coriander, and lemon instead of lime (though i thought it was delicious before i added this too!) Will definitely be making again.

This is an absolute fave. I'm glad sweet potato season has come round again!

Great soup. Thanks to all the commentators advising against grating - saved a LOT of time. I doubled the curry powder & used skim milk. Will definitely be making again.
