I'm sure that on slow cooking threads, Bethannie - who else?? - has mentioned adding thickening granules to the slow cooker pot. I don't know where to buy these. I seem to remember seeing them in supermarkets in the past. I am sure Beth doesn't mean gravy granules which of course I never use to thicken sauces (winky smiley icon) but ones which thicken without adding a flavour - like a powdered roux. Does anyone know where I can buy these. Or has Bethannie made it up?
