Whilst trapesing around the supermarket recently I came across a packet of this

and thought it might work in a brew. Chatting with the guys at the last Cambridge beer meet a Porter was suggested as a good vehicle for it.
Based on Gail Porter, which seems to go down very well, here's my coconuty take on it.
Size: 25.0 L
Mash (90 mins):
5000g MO malt
450g Chocolate malt
240g Black malt
50g Coconut cream block made up with 100ml water
Boil (90 mins):
34g Northdown - 90 mins
10g Goldings - 15 mins
1 tsp Irish moss - 15 mins
10g Goldings - after boil
Windsor yeast.
Any thoughts?
Cheers,
Jamie
