The appetiser fly was originally tied to represent the fry of roach and developed by Bob Church , probably one of the first patterns incorporating marabou which is now very widely used in many streamer patterns, most often fished on a sinking line with a stripping action, generally a good all round attractor.
'I designed the Appetiser in 1972 especially for the big, fry-feeding trout at Grafham. It was the first time marabou was used in the wing of a modern lure in Britain. It had tremendous success at Grafham, topped by taking the heaviest bag-limit for seven years. The Queen Mother is another reservoir where I have had great results with the Appetiser. Indeed, it works well on all water and has been one of the most successful catchers of big trout...'
