Years ago in Atlantic City ,N.J. I bought a hotdog and and the vendor put a pink onion sauce on it,never forgot that sauce.Anybody have that recipe or hear of it?
This is one that was posted sometime ago on this site that was an onion sauce. It would probably be pink, but it is a New York push cart sauce. Would it be similar to what you are looking for?

Dash of Hot Sauce* and Salt
1 cup water.
Saute the onions for about 7 minutes. Add the ketchup, cinnamon, and chili
powder, salt and hot sauce.
Add the water and bring to a boil. Lower the heat and simmer for 10 minutes.
(cook it longer and it gets nice and thick)
- Add more Hot Sauce to your liking for more heat. Bet it is even better
