Chicken with Verjuice Aioli, Iceberg Lettuce, Eggs, Capers and Olives

Aioli: Put the egg, egg yolk, mustard, garlic, tarragon and verjuice in a food processor and combine. With the motor running, slowly drizzle in the combined oils to make a thick emulsion. Season well. Add more verjuice if required to give a pouring consistency. Refrigerate until required.

Chicken: Slice the chicken breast horizontally, to give two even-sized pieces. Season. Heat a little olive oil in a sauté pan and cook both sides until cooked through. Remove to a plate. Add the verjuice and boil until reduced to a syrupy glaze. Return the chicken to the pan and turn to coat. Set aside to cool in the pan juices.

To assemble: Cut the lettuce through the root, into 6 wedges. Arrange on a serving platter.
Slice the chicken thinly against the grain and toss with the pan juices. Arrange on the platter amongst the lettuce, along with the eggs. Drizzle everything with aioli and scatter over the capers, anchovies, olives and flat-leaf parsley. Serve the remaining dressing separately.

Verjuice: in the 14th and 15th centuries French cooks used this juice made from unripe grapes. It has the tartness of lemon and the acidity of vinegar, but without the harshness of either. It marries particularly well with nut oils. Use it to deglaze pans, make vinaigrettes, or poach fruit in a syrup made from equal parts verjuice and sugar. Use white wine vinegar as an alternative in vinaigrettes or white wine for sauces or sweet applications. Verjuice is available from specialty food stores.

*Or substitute 1 cup of good quality bought aioli. Stir in 1 teaspoon of dried tarragon.
