'extremely floury' is the definition.
I can't tell whether this defines the answer.

'pork pies amidst eatables' is the wordplay.
'pork pies' becomes 'lies' (I've seen this before).
'amidst' is an insertion indicator (amidst can mean between or within).
'eatables' becomes 'meat' (meat could historically mean food of any kind).
'lies' put inside 'meat' is 'MEALIEST'.
