I love latkes.
.
The traditional way was to fry them in schmaltz which is chicken fat. Wikipedia says it also can be goose fat. Latkes are served with apple sauce and sour cream. I always put one or the other on them. But These Jewish gangstas put both on at the same time which kinda ruins it with clashing flavors
My guess is there are still hard core Jews frying them in schmaltz which is also what makes knishes taste so good. At least back in the day.
