I'm lazy and cook my porrige in the microwave and what I do is put raisins in first, then the oats and the milk and then stick them in the microwave - what this does is cooks the raisins in the milk, so that when you stir it up you get the sweet taste - fortunately I actually like the taste of porrige so this is more than sweet enough for me. Failing that you could try mixing in some other frozen/dried fruits, and see what works best, because honey is all fine and well, but it's still really really sugary. Fruit sugars are a lot better. I've always wondered what cooking porrige oats in a low fat milkshake would taste like though... stir in some nesquik!!!

(I LOVE nesquik). I'd try it myself, but it's too warm to be eating porrige in the mornings.
