(My grandmother made donuts once a year on 'Fat Tuesday'.)
.
"This is a traditional German recipe, usually made on
Shrove Tuesday to use up the lard before Lent begins.
Don't worry, you can fry them in vegetable oil instead of lard!
Either way, they're delicious!"

::Burn off the extra calories by making the effort to make your own donuts!::
~~~~~~~~~
False, sorry. Calorie “burning” does not work like that.
But lucky you that your grandmother made them for you.
Those look delicious!
But why would you? :)
I will walk to my local bakery on that day for a nice Maple glazed. I walk because otherwise donuts make my clothes shrink.
