Cost information for the following is not included. Normally this is because the quantity or ingredient is unknown
14 -16 key limes, washed and cut in half, juiced to get 1/2 C
1 regular lime zested to get about 1 Tbs
4 pasteurized-in-the-shell egg yolks (only - save the while for other uses)) (you'll see a red 'P' on each shell. Its not uncommon to find them in stores. I don't recommend them for scrambled or any cooked eggs, but in this recipe, you don't bake the filling and you want to risk unpleasant episodes with your guests)
