The Chinese Kung-Pao sauce usually is used as a marinade for a stir-fry dish of beef, chicken, or shrimp stripes and vegetables. The flavors are spicy, sweet, and savory. This recipe will teach you how to make the sauce, but we suggest using it as a full-steak marinade. The flavors are deep and not as pungent and rich as the BBQ sauce, but they sure are hot and spicy! This mix will work perfectly for marbled beef slabs (think Ribeye, Strip and Sirloin).
