This was insanely delicious! Definitely going into my list of favourite recipes for when friends are over. I first baked in a deep casserole dish but found that only the top layer was really cooking, so transferred halfway through to a larger, more shallow dish, which seemed to work much better (and baked more quickly).

Absolutely delicious! Only change: after blending I sieved the coconut-Lemon-grass mixture as I wanted a smooth texture. I'll have that again very soon.

Delicious gratin with an extra kick from the chilli, lime & lemon grass .. loved by all & even 2nd portions served up .. I added a little bit of grated cheese to the top which worked well .. great recipe to use up some boring veg (ie. potatoes) .. will definitely make it again but don`t think I`ll add the chilli seeds which I did on this occasion
