What's up with these countries and the shitholes of the body? Liver, intestine, kidney…the list goes on. The most common explanation I've heard (and I tend to agree) is that these cultures have only recently been able to not waste valuable protein sources like vital organs. Western cultures have an abundance of food not found in other countries, and given the "acquired taste" of some of these organs, they just lost their popularity as simpler meats grew more accessible.
Whatev. On to taste.
Taste:
Kidney, like liver, has a very, very distinct aroma and taste. It might be a tad bitter (maybe a figment of my imagination). It's funny how our expectations of certain things can alter how we experience them.
In any case, I won't try to describe the aroma. Like liver, it is best called "unique" and "pungent." And also like liver, it is also very much an acquired taste.
The texture of kidney is a very interesting thing. You'll notice that there is a crosshatched cut pattern on the meat. Apparently, kidney is so easy to overcook into inedible toughness that cooks score the meat so that it cooks easier. The result is a meat that has a small, soft "snap" to it when bitten--there is relatively little give in the meat as you bite into it before a piece breaks off. It's an interesting texture, and altogether not at all unpleasant.
Reflections:
Not terrible, but not my cup of tea. I've had kidney on several occasions, and have never really gone to take that second piece from the lazy susan. The meat was prepared well as far as I can tell, but it's just too much of an acquired taste. Rather, it's too much of a foreign taste for my American taste buds. Not a bad experience though...
