I am compiling a sandwiches cookbook, or sarnies as we call them in the UK, and here is my first recipe! Sandwiches come in many guises, from simple and elegant to hearty and robust; in my cookbook I aim to have them ALL in there! Sandwiches tick all the boxes for so many meals and events: the obvious high teatime table, cricket teas, picnics, packed lunches and quick snacks. These sandwiches are dainty and elegant and would be ideal for the teatime table. The use of fresh chives gives them a bit of a lift and you must try to use the salad cream as well as the mayonnaise; salad cream has a pronounced vinegary flavour which cuts through the richness of the mayonnaise and eggs.
