I am a big fan of citrus, especially lemon and lime. Lemon meringue pie, key lime pie, anything really, with lemon or lime really gets my taste buds going, so when I saw this fantastic recipe by Liz from That Skinny Chick Can Bake I bookmarked it immediately.
It turns out that a matter of days later I was requiring three egg whites for something, leaving me with three egg yolks needing used up, and lo' this recipe calls for precisely three yolks. I had seven tiny limes in my vegetable crisper so there was no excuse for me not to try it. As an aside, are UK limes a miniature version of the American ones? I needed the juice of seven limes to make up the required quantities, but the luscious looking limes in Liz's photographs look massive! I bet she only needed three or four.
This is a remarkably simple recipe to make. Crushed digestive biscuits (or graham cracker crumbs if you live in North America) are combined with coconut, a dash of sugar and some melted butter to make a gorgeous coconut crust and the topping doesn't involve any stovetop cooking, as most recipes of this type I've encountered do. Just whisk the ingredients up, pour over the base, bake to set and then chill. It really does improve after an overnights' chilling. I cut out one bar after the four hour period and the crust was still a bit too crumbly, but after overnight it was perfection.Liz has very kindly given me permission to reblog her recipe using UK measurements and as it is a bookmarked recipe I am entering it into Jacqueline from Tinned Tomatoes' Bookmarked Recipes #24 roundup for May 2013.
