Sabrett Onions in Sauce for hot dogs recipe

Here’s a cool copy for the tangy orange/red onion sauce slathered
over hot dogs ordered from Sabrett push carts. For a buck or two
you can grab a hot dog with the works on the fly from these popular
umbrella-covered food carts in many major cities. You find hundreds
of ’em in New York City, especially around Central Park
(that’s where the sample for this re-creation was obtained).
While most of the Sabrett toppings are standard hot dog fare
– ketchup, mustard, sauerkraut – the onion sauce is a real
Top Secret Recipe. And it’s one that we can now slam into the
“solved” file.
