in the kitchenThe filler
also: the injector · the nozzle · the pump
You can hear a filled donut being made: a thump and a hiss, once per piece.
A hand pump or bench machine that pushes jam, custard or cream through a nozzle into the side of a fried round.
The story Cited · wp-jelly-doughnut
Filled fried dough is older than the ring — Gefüllte Krapfen are in a Nuremberg cookbook of 1485 — but the injector is what makes a case full of them possible before six in the morning. Fillings run to fruit preserve, custard, Bavarian cream, and in Polish shops powidła, stewed plum, and wild rose petal jam.
How it is done Tradition
Fry, cool, weigh the first few to set the dose, then work a tray at a time.
Today Tradition
A filled donut does not hold overnight the way a glazed ring does, which is why it is the one most often made last and sold out first.
