I believe the answer is:

hot mustard

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

'condiment' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'dartmouth's jarred' is the wordplay.
'jarred' is an anagram indicator (I've seen 'jars' mean this (the letters must be shocked or jarred)).
'dartmouths' anagrammed gives 'HOT MUSTARD'.

Can you help me to learn more?
