I made a version of this dish the other night and it was delicious - my good lady wife said so and she's always right!

I say "a version" because I had a quantity of the Zaal red masala sauce handy, so I used that instead of the recipe sauce.
Good tip about the Tandoori paste, CT - I see that Tesco aren't currently stocking Patak's tandoori paste but have Laila instead. I bought a jar but haven't used it yet, so no idea what it's like.
Slightly off-topic - I took a selection of spices and mixes with me on holiday recently including CA's tandoori mix powder because I knew I wouldn't get any where I was going and I wouldn't be able to take any paste with me on the plane. I just mixed the dry spices with a little vegetable oil and let it stand for a while before using it. Seemed to work OK and the grub was up to standard. Pity we couldn't replicate all the Patak's pastes in the kitchen, but I know that's been discussed elsewhere.
Back on-topic - I'll definitely make your Tuk Tuk again, CT, but to spec next time. Looking forward to it, in fact.
