Langoustine, Potato Puree and Soured Cream

This dish is completly different from what we would normally cook, so looked forward to the challenge.  I was a bit scared with the amount of stages to be completed, again I tend to try and make quick and simple dishes.  However, the challenge was accepted.

Every step was simple, apart from smoking the potato, so in true lazy fashion – we skipped that! The leek ash was another new bit.  I’d never heard of this so a bit of googling and found this, which sorted that stage out.

Verdict? A lot of effort, but at the end you get a light summer meal which uses some delicious seafood.  I’d love to try the champagne cream with some salmon and dill.
