Does anyone have a tried and true key lime tart recipe? I'm actually hoping to make tartlettes (approximately 1.5 inches in diameter) or tarts (approximately 3-4 inches in diameter) so if you have a recipe for those it would be great, but if not then I can just adjust the full-sized tart recipe accordingly. I've made key lime curd tartlettes before that involved adding the prepared curd to a cooked (homemade) shell, and piping stiff meringue on top. They were great, but I'd prefer to have the whole thing be homemade, as in that case the curd was purchased.
Alternatively, does anyone have a good key lime curd recipe, and is this a good time to be making this sort of thing? I know citrus fruit is in season this time of year, but for some reason when I think of key limes I think of summer and sunshine, so I have no idea if fresh key limes are good at this time of year, or whether I'll need to use a mixture of lemon/lime juice to imitate the key lime flavor in my recipe.
