Chicken with mushrooms and lemon grass

My daughter, who is a smoker, likes blow your head off spicy food, so, thinking of her, I disregarded Nigel's direction to deseed the 3 hot red chillies and instead left them in. Cor! The heat was intense - I'd used scotch bonnet and they were seriously hot, but it did the trick and we both enjoyed our meal tonight. I had an emergency right at the end of making this when the lime I bought for it was dry as a bone. I made do and mend with a lemon and it didn't seem to make any difference.
