Choose a heavy pot or Dutch oven with a tightfitting lid. It should be large enough to hold the chicken snugly, but not much bigger. Fill pot about ⅔ full with cold water, but don’t put the chicken in yet. Boil some extra water in a tea kettle.
4 lbs Chicken Breasts
Add scallions, peppercorns, chicken bouillon (if using) and salt to the water, cover and bring to a rolling boil. Turn off heat and slip chicken pieces into the hot water. If needed, add boiling water from the kettle to cover chicken with water by 2 inches.
3 Scallions, ¼ teaspoon Black Peppercorns, 1 Tablespoon Better than Bouillon Chicken Base, 1-2 Tablespoons Salt
Replace the lid and let chicken rest in the hot water for about 2 hours. Do not turn the flame back on: The pot will retain enough heat to cook chicken thoroughly and safely. (To test, cut into 1 piece of chicken and check the meat near the bone. If it is still pink, return the pot to low heat, bring the water to a simmer and simmer 10 minutes more.)
Lift chicken out of the pot. Remove and discard bones, skin and fat. Pat the meat dry with paper towels, then cut or shred into small bite-size pieces and transfer to a bowl. (Meanwhile, simmer cooking liquid until tasty, strain and refrigerate or freeze to use as chicken stock.)
In a bowl, whisk together the juice of ½ lemon, mayonnaise and sour cream. If using, whisk in mustard. Taste and adjust the seasonings and thickness to your liking. Pour over chicken, scraping the bowl clean with a rubber spatula.
½ Lemon, ⅔ Cup Mayonnaise, ¼ Cup Sour Cream, ¾ teaspoon Dijon Mustard
Add all the herbs and season with salt and pepper. Toss gently but thoroughly. Refrigerate, covered, at least 4 hours.
2-3 teaspoons Fresh Tarragon, 2 teaspoons Fresh Parsley, 2 teaspoons Fresh Chives, 1-2 teaspoons Fresh Dill, Salt and Ground Black Pepper
Taste and add salt and pepper as needed. Sprinkle with herbs before serving with croissants.
