'chaos' is the definition.
(I've seen this before)

'eric leaving spice and cooking ingredient in' is the wordplay.
'leaving' indicates named letters should be taken away.
'spice' becomes 'turmeric' (I've seen this before).
'and' is a charade indicator (letters next to each other).
'cooking ingredient in' becomes 'oil' (I can't explain this - if you can you should believe this answer much more).
'turmeric' with 'eric' taken away is 'turm'.
'turm'+'oil'='TURMOIL'
