I use this for pieces:
1/4 cup coarse salt
1/4 cup packed brown sugar
20 black peppercorns, or equivalent powdered
2 bay leaves
small onion sliced thin
2 cloves garlic mashed or equivalent powdered
Combine the salt, sugar and pepper in a dish. Stir in 1 cup of hot water and mix until the salt and sugar is disolved. Then stir in 3 cups of cold water. When the mixture is about room temperature, add the onion, garlic, bay leaves and chicken. Let it sit in the fridge for 2 hours, turning once in awhile.
Tastes great.
