Tony, did you use the original 5 ingredient recipe or one of the modified recipes (like Rory's posted above)?
My two cents. I have made my own sauces all my life until Sweet Baby Ray's came on the market. #5 sauce is the first sauce I've made in over a decade, its still simmering now and it's not going on Q until tomorrow but I like it! I made it exactly per recipe, next time I'll add less vinegar and try some chilli sauce in place of some ketchup and some heat, probably Cayenne, but it's a damn good base! Highly recommend!
No. 5 Sauce
1 cup ketchup
1/2 cup cider vinegar
1/3 cup brown sugar
1 tablespoon worchestershire sauce
1 tablespoon rub
Opional but v. good: 1/4 cup meat drippings
(whats left in the foil after the rest)
Simmer to marry the flavors and thicken as desired.
P.S. My rubs are low salt.
I too am a big sweet baby rays fan. However, on PB and after making this #5 sauce...wow...I really liked it. It's a light but string flavor if that makes any sense. I think you are right on. I was wanting just a hair less vinegar (liked it just fine but want to try less) and I also was thinking chili sauce might make a good replacement for ketchup. We do the same thing in our meatloaf.
If you like sweet BR sauce, add some brown sugar and quite a bit of onion powder...great on Ribs!
Rusty, you are supposed to use your favorite rub. It makes the sauce uniquely yours. I use Benoits Cajun seasoning in mine...
