If the mixture is too runny then add more flour to the mixture. If it becomes to thick add a little more water.
If you would like to add mushrooms, slice a handful and add 30 minutes before eating!
Made this today and doubled up on the recipe. I added some chilli flakes for spice - love spicy food!! :-) Bought caramelised onion sausages from Sainsburys and the result was amazing!! This dish is a real winter warmer and was very easy to do. My other half was amazed that I made this as I'm a useless cook!!!!! - 04 Nov 2012
