Sweet Potato Pancakes

I made these for pancake day and they were delicious. I fancied making them again and as the veggie stall gods had it sweet potatoes were on special offer this week. I used some of them yesterday in my spinach and sweet potato dahl and had just the right amount left to make these pancakes. I exchanged the melted butter for 100ml of semi-skimmed milk to bring the calorie count down a bit. They worked pretty well and were delicious with a bit of honey on them.
