Let chicken warm to room temperature. Wipe with a damp cloth.
In a wide bowl, beat egg with buttermilk.
Place flour, salt and peppers in a brown paper bag.
In a large skillet (preferably cast iron) heat lard and shortening.
Dip each piece of chicken into
the buttermilk-egg mixture and place in a brown paper bag. Close
top of bag and shake until piece is well coated. Remove, and repeat
for each piece.
When shortening is hot (375 degrees F on
a deep-fat thermometer), ease chicken into pan and cook over high
heat, turning so both sides cook evenly. Do not crowd more than
a few pieces of chicken into pan at one time. When chicken is light
gold on both sides, turn down heat to low and partially cover skillet.
Cook for 15 minutes, turning chicken once.
