We used to have a German Beer garden restaurant in Frederick, I think the one is Leesburg is still open, Donner Bistro I believe it was called. They had curry ketchup and that shiz was the bomb! Used to get one of their Donner cups with fries and shawarma with a side of knockwurst and drowned it in curry ketchup. Need to learn how to make it. I make my own Alabama white sauce for grilled chicken.
We obsess over Old Bay that is all you need to know.
Now I am researching GF liquor this morning.
