How is a burger different from a patty?

How does a burger differ from a patty, other than its shape?

As an example, a bun with jam and a pie with jam, what is the difference besides the shape?

A bun is always baked goods. And the pie can be fried or baked.
In shape: is the bun usually round, like?
And according to the location of the jam, kmk: a bun can have jam on top, and a pie is always with jam inside.

And the pie is like a cheesecake, the jam is on top, it seems to be not a bun, but a bun all the same if the jam is inside, and the pie can be inside and on top, it seems to me so

A bun is always baked goods.

Nastya, what about yeast donuts?

The same round fried bun). Only small.

And also the difference in the ratio of dough and filling, in buns there is little filling, in my opinion, but a lot of dough. For me, in principle, a bun, this is without filling, it is possible with raisins, but this is a filling distributed in the dough

A bun is a bakery product without a filling, that is, there are also filling, but mixed into the dough. The pie is always stuffed inside, it can be fried and from the oven, the buns are only baked. Cheesecakes are not pies or buns, but cheesecakes.
It's like borscht, borscht always happens with beets and cabbage, without cabbage, beetroot, without beetroot, but very often they call it borsch even without cabbage even without beets, which is wild for me (my mother-in-law calls it that and how to deal with it) ... Potatoes are not required for borscht, but cabbage and beets are.

Just in the last program "Let's eat at home" Vysotskaya said that her grandmother on the Don called cabbage soup with tomatoes, and with beets, what we have borscht called beetroot. Your mother-in-law probably also took local names from her childhood. Let her not have to fight (what is it interfering with you?), She is so familiar and correct, she cannot suddenly imagine in her old age that all her relatives and all her relatives have been saying wrong all her life. You are not her teacher, but her daughter-in-law. Learn your children correctly, they will remember everything and will know why grandmother says so. No problem, the country is big and there are many local names.

(Does this bother you?)

To be honest, yes. According to GOST, I don't even know why, but it's not nice.

Nastyusha, what about yeast donuts

And this is no longer a bun, but a donut.

It's like borsch, borscht always comes with beets and cabbage

nope .. borscht is borscht, even if it is green ... I learned about it at the Culinary School from Gali - Gray Dog

And I'm from a cook's college. And from the thick GOST book.
in general, borscht originated from borschivik - yes, but it was a long time ago, a long time ago in one word.
