Taste of Scandinavia – Langoustine with potato puree and soured cream

Scandinavian food very appealing to me as they use a lot of Omega 3 rich fish and seafood. When I was challenged to reproduce this Langoustine with potato puree and soured cream dish by the chefs at Aveqia, I had to attempt it. Having been to a cooking lesson there, I knew that their recipes are quite involved and use a lot of different cooking techniques. I love learning new cooking techniques but without someone instructing you over the shoulder, this can be quite tricky.

So armed with just a recipe with one image of the final product, I set out to recreate this recipe. There are quite a few steps, a lot of ingredients and takes a bit of time. The resulting dish was quite delightful. There weren’t any difficult techniques to learn and no special equipment was needed. The original recipe involved smoking the potato puree which I skipped.

Instead of using Langoustines, prawns were used instead. (You can get frozen langoustines in Sainsburys.) I did use up quite a few pots to make the various sauces and lots kitchen equipment that I don’t usually use. It is certainly a lot more complicated than my usual one pot recipes.

The recipe did not give any details about plating up and how to use the various sauces and champagne cream so you can just make up your own version.
