I have a bunch of citrus left over from a cocktail party - about 12 lemons at 3-4 tbsp juice each and 18 limes at 1-2 tbsp juice each. They need to go! So far I've thought of lemon meringue pie, but that uses only 2-3 lemons. Any other ideas? I don't think the limes would be suitable for key lime pie as they are the relatively bitter persian variety, so I might dry them, but that still leaves some to be reckoned with.
