With more words added, in `[square brackets]` -

> He liked his [bagels] warmed, though on TV ads he would [eat] [his bagels] toasted, the butter [on the bagels] just melting, with an irresistible crunching sound [as he ate them].


I'm inferring that the man in question (call him *John Doe*) is a TV spokesperson for the bagel company, who is portrayed on TV as liking his bagels toasted. However, back in reality, he prefers his bagels simply warmed, not toasted.

**You, the reader, are supposed to infer that the subject of this sentence is John's Bagels.**

We can guess at more context:

> John Doe was a TV spokesperson for the Generic Bagel Company.  
>
> He liked his [bagels] warmed, though on TV ads he would demolish [his bagels] toasted, the butter [on the bagels] just melting, with an irresistible crunching sound [as he ate them].

My spellchecker is complaining about the <kbd>though</kbd>, claiming that it should be <kbd>through</kbd>. Don't worry, <kbd>though</kbd> is correct here.
