Just a quick question - your food looks yum and I really want to have a go at key lime pie, but there are two ingredients we can't get in the UK - key limes and graham crackers. Now I can probably get hold of a bottle of juice, so I guess when it comes to cooking the pie, I'll just have to play with myself as I won't have to juice the limes myself (and if I can't, the whole thing kind of becomes made of fail anyway) but what would be a good substitute for the cracker crumbs? I suppose I could crush digestive biscuits (that's what I normally do for cheesecake etc.) but would they be too sweet?
