OK, so here's the scene - I get out my banoffee pie recipe, I put my can of condensed milk in the saucepan to boil, the doorbell rings and it's the girl next door looking for a recipe for mushroom stroganoff. "Oh, I have one in this recipe book here", say I, and lend her the book that the banoffee pie recipe is in.
Fast forward a couple of hours and I can't remember how long I have to boil my can of milk for. "I know", thinks I, "I'll pop round to see if she's finished with my book yet" ... just as I see her driving off in her car.
So, I turn to MN ... someone must know whether it's three or four hours I need to boil the can for? Mustn't they?
Please?
