Preheat the oven to 130c/Gas 2 (a cool setting)
Place the rolled oats in a bowl and mix in the nuts, seeds and coconut. (not the raisins yet!) Stir well.
Warm the honey and oil together in a small pan and pour onto the dry mixture.
Coat all the nuts, oats, seeds etc in the honey and oil.
Spread the mixture onto a baking tin and place in the oven for 40 mins. You will need to move the granola around a little from time to time to ensure that it crisps all over.
Remove from the oven and mix in the raisins. Leave to cool and store in an airtight container. where it will keep for several weeks.
