Salt's ruined important meal with terrible consequences? (4,6)

I believe the answer is:

last supper

'meal with terrible consequences?' is the definition.
(reference to Jesus' Last Supper)

'salt's ruined important' is the wordplay.
'ruined' is an anagram indicator.
'important' becomes 'upper'.
'salts' with letters rearranged gives 'lasts'.
'lasts'+'upper'='LAST SUPPER'

I've seen this clue in The Telegraph.
