This is based on the chicken sandwich served at Harry's Bar in Venice, Italy. Its mounded shape is reminiscent of a Venetian bridge.
1 Mix shredded poached chicken with an excellent mayonnaise, preferably one you have made yourself from egg yolks and oil.
2 Add a squeeze of fresh lemon juice. Season well and add lots of ripped fresh basil leaves.
3 Shed some iceberg or cos lettuce.
4 Set out sliced white bread with the crusts removed. Spread these with a thin layer of mayonnaise. For this substantial sandwich I use toast-cut, not sandwich bread.
