Hi Anne.
We love porriage in our house and have it most days in winter. I find that
if you turn the speed up a little to 1.5 - 2 then it doesn't seem to catch on the bottom as much and the covering the blades with water and turning up to speed 9 slowly seems to do the trick with the cleaning afterwards. I do find that with most recipes the
function is the one that can cause things to stick. I have found that if you look through the TM lid hole and you can't see the top of the food moving a bit then just crank the speed up a little. Also with the bread, being your winter you can prove it in your oven at 50oc with a teatowel over the top of your dough. If you use the same tray that you are going to bake your bread on there wont be extra washing up to do.
Cheers
