^Tried that, and normal vinegar too (a bottle of each with just a few tablespoons out of them hog room in my kitchen cupboards with no further use), and vortex / non vortex methods too. In fact if there's a Youtube vid of how to cook the fucking things perfectly I've likely had it playing on my Tablet in the kitchen while trying to copy what they're doing.
If at first you don't succeed, try try try again. If after that you still don't succeed, go to a local eatery with some cvnt in the kitchen that can cook them perfectly :)
