BASQUE MEAT TENDERIZER BBQ SCE The Original. Real Basque. If you try me, I know you will like me. I am all natural. I work exceptionally well with poultry, beef, lamb and pork. If you want to experiment, I will be more than happy to assist you. For better and tastier results allow me to marinate meat for 4 to 5 hours. Be sure to cut small slits on poultry so I can penetrate and tenderize. On the grill keep me busy by basting. Let me be your secret when marinating, roasting or sauteing. Be creative! The seasoning for all seasons!
