"Don't they carry one back to all one's parties?"

In Katherine Mansfield’s The Garden Party (1921), there is this question I cannot decipher semantically nor grammatically.

In this scene, this high-society family is preparing a garden party. Cream puffs are delivered, and Laura utters the question in bold in the text below:

"Godber’s has come," announced Sadie, issuing out of the pantry. She
had seen the man pass the window.

That meant the cream puffs had come. Godber’s were famous for their
cream puffs. Nobody ever thought of making them at home.

"Bring them in and put them on the table, my girl," ordered cook.

Sadie brought them in and went back to the door. Of course Laura and
Jose were far too grown-up to really care about such things. All the
same, they couldn’t help agreeing that the puffs looked very
attractive. Very. Cook began arranging them, shaking off the extra
icing sugar.

"Don’t they carry one back to all one’s parties?" said Laura.

"I suppose they do," said practical Jose, who never liked to be
carried back. "They look beautifully light and feathery, I must say."

What does it mean to carry one back in this context? And to all one’s parties?

It’s also confusing the following play on words, I assume, by Jose. He never likes to be carried back…?

Is this word usage something characteristic of British English, or an archaic expression?
