The Vaad of 5 towns used to have the mashgiach light the fire. Then they stopped. The Star K relies on the same heterim for their Krispy kreme. Alas, my rav will not let me eat there. Better for my wallet and tummy though.
I was at a fancy chasunah last year around chanukah time. They served donuts for dessert- all types, not just sufganiyot.
