White Chocolate, Craisin and Lemon Muffins - Perfect for The Lunch Box

I had some Buttermilk in the fridge.
I had bought it for another recipe, 
It was part of the delicious dressing for The Indonesian Chicken Salad
A wonderful  dish click here
I only used a small amount and there it was sitting in the fridge, doing nothing
There has to be something interesting
I subscribe to the Good to Know Website and I found this recipe
It called for blueberries, I replaced them with Craisins
This proved to be very popular with the kids and the whole dozen went in one sitting

150g caster sugar    
250g self-raising flour
1tsp baking powder
100g butter, melted
1 medium egg, beaten
284 ml buttermilk
1tsp vanilla
 Zest and juice 1 lemon
 200g white chocolate, chopped
 180g Craisins

Heat the oven to 180C fan
Line a 12-hole muffin tin with paper cases.

Mix together the caster sugar, flour and baking powder, 
then pour in the butter, egg, buttermilk, vanilla and lemon zest and juice. 
Mix well, then fold in the chocolate and the Craisins

Spoon the mixture into the prepared muffin tin

Bake for around 20-25 mins,
until golden and springy.
