Popular sauce is revolting and dry (7)
I believe the answer is:
insipid
'dry' is the definition.
(I've seen this before)
'popular sauce is revolting' is the wordplay.
'popular' becomes 'in' ('in' can mean trendy).
'sauce' becomes 'dip' (sauce which food is dipped into).
'revolting' is a reversal indicator.
'dip'+'is'='dipis'
'dipis' in reverse letter order is 'sipid'.
'in'+'sipid'='INSIPID'
'and' is the link.
(Other definitions for insipid that I've seen before include "Lacking taste or flavour" , "Lacking in flavour or interest" , "devoid of flavour" , "Very weak" , "Boring and lacking liveliness" .)
