Here's a simple one, but a goody nonetheless. I was inspired to rustle this up after seeing it on my friend Rene's blog http://www.renehumphrey.blogspot.com/
Basically pop a jacket potato in the oven (after pricking all over, and smearing with olive oil and sea salt) for 1-1/2 hours.
Meanwhile put a 150g packet of cooked, peeled king prawns into a bowl. Add two generous tablespoons of creme fraiche, the juice of half a lemon, just under a handful of chopped dill, and season. Mix it all together then pop back in the fridge.
Serve with the potato and some salad. This amount of prawns will serve two, but I kept half and had the rest on a toasted bagel for lunch today. Delish!
