This may be hot - had better put on a raised bar inside (7)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

MUST (had better? – I’d interpret that as a strong recommendation rather than a requirement), before (above, in a down clue = put on) A + R [aise] D (bar the inside = without the inner letters). A condiment that may be more or less hot depending on the variety.
