אֶפְרַ֕יִם בָּעַמִּ֖ים ה֣וּא יִתְבּוֹלָ֑ל אֶפְרַ֛יִם הָיָ֥ה עֻגָ֖ה בְּלִ֥י הֲפוּכָֽה׃
Ефрем, он смешивает себя с народами; Ефрем превратился в торт, а не превратился.
Rashi on Hosea
as a cake which was not turned over Jonathan renders: as a cake which, before being turned over, was consumed. עֻגָה is a cake which they bake on the coals.
