Food blog designed to support resort (4,3)
I believe the answer is:
spag bol
'food' is the definition.
(short for spaghetti Bolognese)
'blog designed to support resort' is the wordplay.
'designed' indicates anagramming the letters (designed with the letters).
'to support' is a charade indicator (letters next to each other) (in a down clue, some letters hold others up).
'resort' becomes 'spa' (spa is a kind of resort).
'blog' with letters rearranged gives 'gbol'.
'gbol' after 'spa' is 'SPAG BOL'.
(Another definition for spag bol that I've seen is " Simple meat and pasta dish (abbr)".)
