I managed to mess up this cocktail in a fairly interesting way. My one remaining lime only had 1/2 oz of juice left, and in an effort to balance it out, I added some lemon juice as well. I realized after adding it that I had added 1/2oz of each, so a bit more acid than called for. I balanced it back out with a splash more orgeat and on a whim I added maybe 1/8oz of Cruzan blackstrap. I went light on the mezcal. At first taste, I could have sworn I tasted a smoky/savory food like a sausage gumbo. I added a very light float of the cruzan, and oddly enough, after it settled out again it gained an intense sour lemon flavor- almost identical to a lemon drop candy. It was quite unexpected and yet quite enjoyable.
I don't feel like I can pass judgement/ rating on this recipe, but it's clearly a flavor bomb and the ratios can be adjusted to interesting results.
