Regularity of texture (11)

I believe the answer is:

consistency

I believe this clue is a double definition.

'regularity' is the first definition.
(thesaurus)

'texture' is the second definition.
(thesaurus)

'of' is the link.

(Another definition for consistency that I've seen is " Thickness".)

I've seen this clue in The Times and The Sunday Times.
