This was a good recipe, but it needs to be tweaked. The proportions of this recipe are off. It calls for too much lemon juice and possibly crab - the lemon taste overwhelmed as written! I would cut lemon juice in at least half. Better yet, don't even measure it, just add a little at a time and keep tasting it. Really, it's only there, I think, to stop the avocado from browning.
I also added more chili flakes than it calls for, and you could probably add more if you like spice.
I was assembling this into a 2 oz. shot glass. I put a little bit of the avocado mixture on the bottom, then layered it with drab and garnished with the sliced avocado. I had a ton of crab left over. I purchased 24 oz. of lump crab (I was making 32 shooters - so scaling the recipe up 4x) instead of steaming and cracking my own legs. I probably had half the crab left over. So, if you're buying lump crab like I did, I'd cut the portion in at least half if you're truly making a shooter. Or, just use a bigger glass, 5 oz.
