Hot?
That's some good stuff!
Of course hot. Or a grilled corn with avocado salad with poblano/chipotle vinaigrette served cold.
Often see a mayo based potato salad sold as "German".
And Iike it.
Wife and I made one pretty much like that last night.
(Along with sauerkraut salad)
But is not real German Potato salad.
Rarely see your dish any more.
Folks don't want to do all the work.
