After cutting and tenderizing your pheasant breasts to ¼ inch, place them in a Ziploc bag with the buttermilk. Let marinate overnight.
Heat oil to 300 °F (I use a deep fryer, but if you have a frying thermometer, a cast iron or any heavy duty deep enough pan will work).
Combine flour, salt, pepper, and garlic salt in a shallow dish (I use a pie dish).
Remove pheasant breast from the Ziploc bag and dredge in the flour mixture. Dunk back in plastic bag buttermilk and repeat the dredge in the flour mixture.
Repeat process for all of the pheasant breasts. Fry in oil for 5 minutes and flip and cook for another 3 minutes (or until golden brown and cooked through).
Assemble your biscuit. Cut biscuit in half. Place pheasant breast and top with honey butter and biscuit top.
*If you do not have the luxury of being near an HEB that carries Whataburger Honey Butter, A great alternative is combining 1 stick of room temperature salted butter and 1/8 C of clover honey.
Tenderizing Help:
Place pheasant breasts on a cutting board. Cover Breasts with a piece of plastic wrap. Hammer the breasts with your meat tenderizer carefully. A little will do A LOT.
