Cook your sausages as instructed on the packet and set aside. *Make sure they're not well done as they'll be cooking for a further 15 minutes later.
Leave the sausages whole if making giant yorkshire puddings or cut in to 3 pieces if making 10 regular one.
Preheat your oven at 230c or gas mark 8.
Spray two 8" non stick cake tins liberally with frylight, or 10 regular Yorkshire Pudding tins and place on a metal tray and leave in the oven for 10 minutes while you make the batter.
In a food processor or blender, blitz the oats and seasoning together until fine. Don't try blending all the ingredients in one go as the oats won't break down as much.
Add the remaining ingredients and blend again.
Once the tins are extremely hot, place in the sausages and pour over the batter in to each immediately, swirling them until all surfaces of the tin are completely covered.
Bake for a further 15 minutes without opening the oven in between and serve.
