Id like to know about the porridge balls too.
To make porridge fingers I put porridge oats in a flat bowl and pour over enough milk to wet them so they go a little soft. Mash the milk into them a bit. You can add any fruit you want eg grated pear, apple, mashed soft berries, raisins. You could put cinnamon or whatever on it too if you want to add a bit more flavour.
Either pop in microwave for a few mins, I copied the BLW recipe but my microwave nuked em!! I just keep an eye now depending how much I'm making.
Or put the mix in an oven proof dish and bake at a moderate heat (again I just keep an eye). I think its 160 on my oven.
Leave to cool, then cut in fingers
