Tasty Turkey Burgers

This recipe is slightly adapted from one I found in Cook's Illustrated. Without a doubt, the best turkey burgers I've ever tasted...

Ingredients

1 ¼ pounds 93% lean ground turkey (I use Shady Brook Farms)
½ teaspoon salt
½ teaspoon ground black pepper
2 teaspoons Worchestershire sauce
½ cup whole milk Ricotta cheese
¼ cup Italian seasoned breadcrumbs (I use Progresso)
2 teaspoons Dijon mustard
1 tablespoon vegetable or canola oil (for cooking)

Directions

1. Place ground turkey in a medium size bowl. Add salt, pepper, Worcestershire sauce, ricotta cheese, breadcrumbs and mustard and mix until well blended (your hands are the best tool). Divide meat mixture into 5 portions. Lightly toss one portion from hand to hand to form a ball, then lightly flatten ball with fingertips into 1-inch-thick patty. Repeat with remaining portions.

2a. To Cook Indoors: Heat a large, heavy skillet over medium heat until very hot, 4 to 5 minutes. Swirl oil in pan to coat bottom, then add burgers. Cook over medium heat without moving burgers until bottom side of each is dark golden brown and crusted, 3 to 4 minutes. Turn burgers over; continue to cook until bottom side is light brown but not yet crusted, 3 to 4 minutes longer. Reduce heat to low, position cover slightly ajar on pan to allow steam to escape, and continue to cook about 8 minutes longer, flipping burgers if necessary to promote deep browning, until center is completely cooked. Remove from pan and serve immediately.

2b. To Grill: Alternatively, grill burgers over medium-low fire (you can hold your hand about 5 inches above grill surface for 5 seconds) until dark spotty brown on bottom side, 7 to 9 minutes. Turn burgers over; continue grilling 7 to 9 minutes longer or until bottom side is dark spotty brown and center is completely cooked. Remove from grill and serve immediately.
