Bit inside leg, unfortunately not easy to eat? (12)

I believe the answer is:

indigestible

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

'not easy to eat?' is the definition.
I can't judge whether this defines the answer.

'bit inside leg unfortunately' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'bit'+'inside'+'leg'='bitinsideleg'
'bitinsideleg' is an anagram of 'INDIGESTIBLE'.

Can you help me to learn more?

(Other definitions for indigestible that I've seen before include "hard to take in" , "can be hard to stomach" .)

I've seen this clue in The Times.
