Surely someone could translate sufganiyot to doughnuts. This whole module on holidays is virtually useless to someone who knows nothing about them (not me, but others). What is Rosh Hashanah or Yom Kippur? They should give translations and maybe something might be learned here.
No, sufganiyot are definitely distinct from doughnuts and are made quite differently. As an Israeli raised and living in the states I could tell them apart on a blind taste test any day. If you really want to, you can refer to them as "Hannukah doughnuts" and it's certainly easier to explain them to Americans as doughnuts, but they are not the same food.
