Reddish-orange fabric somehow engrained (9)

I believe the answer is:

grenadine

I'm a little stuck... Click here to teach me more about this clue!

'reddish-orange fabric' is the definition.
I can't judge whether this definition defines the answer.

'somehow engrained' is the wordplay.
'somehow' indicates an anagram.
'engrained' anagrammed gives 'GRENADINE'.

Can you help me to learn more?

(Other definitions for grenadine that I've seen before include "material" , "Pomegranate cordial" , "Pomegranate juice syrup" , "Cordial made from pomegranates" , "Syrup - endearing (anag)" .)

I've seen this clue in The Times.
