Seasons Greetings II from Eclogue

All forty clues are letters latent – there are two solutions in each column and row and the letters omitted from the subsidiary indications should be placed in the perimeter square most logically ‘adjacent’ to each.  Each clue also has a misprint within its definition.  The correct letters spell out an instruction to be applied to the central 10x10 section of the grid.  The perimeter can be finalised to realise a hearty rendition, but solvers will find that the corner squares would provide the wrong season and should therefore reverse one word of the rendition to correctly complete this years Christmas card.  The lengths in clues refer to grid rather than answer lengths.
