Tender scallop wontons had a batter that cracked on the tongue then floated off, and were accompanied by a sweet chilli and coconut vinaigrette. My poached breast of guinea fowl actually tasted of guinea fowl, and came in a chive broth with dumplings of sweetbread wrapped in cabbage leaf and made to look like dear little sprouts, and a Gressingham duck breast and leg had a spiced orange and kumquat jus that tasted like Christmas.

You couldn't call this pudding: it was more like foreplay.
