Buying: Pig tails can be found in markets serving Philippine, Chinese, Southeast Asian and Caribbean communities. They should have little odor and the skin should be firm. Here in Southern California the Southeast Asian markets prepare them thoroughly and pack them in foam trays holding 1-1/2 to 2 pounds depending on market.
Markets serving other ethnic communities may prepare them quite differently, sometimes whole tails just de-haired, sometimes a whole tail with a big chunk of pig behind attached.
Prep: Pig tails prepared as shown in the photo at the top of the page need no preparation. Tails purchased from less meticulous suppliers may have some hairs still attached. Just shave them off with a regular razor - the one you shave your face and/or legs with will do fine.
Cooking: Pig tails should be par boiled in boiling water for about 5 minutes and then rinsed. Clean the pot, fill it with plenty of water and the pig tails. Bring it to a boil, then simmer covered for about 1 hour to 1-1/2 hour depending on how tender you want them.
Note that for many recipes, instead of par boiling the tails they are lightly browned. I recommend this be done in the broiler or the grill. Coat them lightly with oil before browning. The problem with browning them in oil on the stovetop is the skin. Pig skin splatters oil around explosively and can make quite a mess.
