Way of cooking meat in France, on vacation (6)
I believe the answer is:
flambe
'way of cooking' is the definition.
(term meaning cooked in spirits)
'meat in france on vacation' is the wordplay.
'meat' becomes 'lamb' (lamb is a kind of meat).
'in' means one lot of letters goes inside another.
'on vacation' means to remove the middle letters.
'france' with its middle taken out is 'fe'.
'lamb' going within 'fe' is 'FLAMBE'.
(Other definitions for flambe that I've seen before include "Pour alcohol over a dish and ignite" , "Of food covered with spirits and set alight" , "Of food, covered with alcohol and set alight" , "Of food, set alight briefly" , "cooked in blazing brandy" .)
