One day when I was waiting for service they ran out of marinade and made a new batch right in front of me. All it was made of was salt and chile and garlic powders(not really hot chile) and Sunny Delight for the liquid! I always thought it was much more complex, but not so as it was easily replicatable. More than 24 hours in the marinade made the meat mushy.
I am reminded of the Cardena's store. Their pre-marinated meat was downright delicious! So I can relate, Smokeat. Glad you discovered the secret. Alternatively, I hope some time you try Chef Merito's carne asada rub. I testify that it is out-of-this-world good. Being in the IE, you should find it quite readily at Stater Bros in the meat dept.
