This was served at our wedding, and was affectionately known as 'red drink'. Leading up to the wedding, we tried all kinds of variations on the drink to find just the right combo of ingredients. (Quality control.)
We had a really shallow pie crust, so this recipe actually made one quiche plus a small baking dish of "crustless quiche".
This will not be the quickest recipe, but this may well be the best crab cake recipe you find.
There are lots of items to make ahead, but it's worth it.
