I usually don't measure anything, so if it is too tangy add more ketchup. If it isn't sweet enough add more brown sugar. If it doesn't have the bite you want add a little more Worcestershire sauce, but just a note ketchup will always calm it down , Worcestershire will always give it bite & brown sugar will always sweeten it up for you. Make it your own.
I Love to mimic things I eat at restaurants.
I got this one from a Mom and Pop Mexican restaurant. It's so yummy and so simple not any spices but salt and enchilada sauce. Red or Green sauce, either will do. Save 1/2 of the meat in freezer for a future dinner.
