I miss the lard-fried cake donuts cake donuts of my youth. They were served by a single baker from the window of a war surplus army bus, painted brown and yellow, parked on Morris Avenue in Elizabeth NJ in the 1950s and 1960s.
These were the donuts of my youth, so I'm biased. Plain or powdered only: no fillings, top icings. Just simple, pure donuts. They were dense/crispy on the outside, practically caramelized (not light "krispy") on the outside, and cakey-crumbly (not gummy) on the inside.
Parents always sent their kids to get a dozen from "the donut man" because he always gave the kid an extra to make it a baker's dozen. You had to eat them hot, otherwise these lardy donuts would turn to lead. But when they were warm, yummmmmm.
Anyone know of any similar donuts today?
