Wow-wee! What a lot of really useful information. That's great. I do like the stacking tray idea. It's funny, I'd forgotten that this is exactly how my mam always stores her root veg, never in the fridge. She has always had one of those deeply unfashionable plastic vegetable racks, which she keeps in her little council house pantry from yesteryear! How funny that I forgot this and ended up using the bottom of the fridge! Curious. So, really the bottom of the fridge is for salads.
I shall try to spread the word of Talyrand to any foodies I know ;)
