Puff Appeal

 Appealing Blackberry & Apple Puff Tart at Carluccios - hardly in season but looks good.

Purple Sauce

 Premier Inn and their new Purple Sauce made from blackberries, cider vinegar with pepper and chillies.  Clever, exclusive, limited time marketing of a product that boosts their breakfast appeal.

Custard Doughnuts

 Maple custard doughnuts and Pear and Blackberry tarts at Balthazar - the tastiest bakery cafe in Covent Garden. @balthazarlondon
