Poaching simply means to cook in a large quantity of liquid. The trick is to make sure that liquid is extremely flavorful, and to include enough salt; then you can serve the finished dish with noodles or rice to sop up the deliciousness. This is simple, yet tastes like something you'd order at a Chinese Restaurant.
4-5 pounds chicken parts (use skinless and boneless if you prefer, but bones and skin will add flavor)
6 whole garlic cloves, unpeeled
4 tsp. salt
6 cups water
Cook all ingredients in a pressure cooker on “high” for 12 minutes, or bring to a boil, cover, and simmer on the stovetop for about an hour.
Meanwhile, thinly slice:
1 lb. mushrooms (oyster are delicious, crimini or plain white mushrooms are cheaper)
Some broccoli, if you wish
When meat is cooked through, shred it and remove bones and/or skin if you wish. Toss in the vegetables and cook for a few minutes more, till everything is perfect.
