Lemon squash

Squash , is a non-alcoholic beverage with syrup used in beverage making. It is usually fruit-flavoured, made from fruit juice, water, and sugar or a sugar substitute. Modern squashes may also contain food colouring and additional flavouring. Some traditional squashes contain herbal extracts, most notably elderflower and ginger. Squash is mixed with a certain amount of water or carbonated water before drinking. The amount of water added is to taste, with the squash becoming less strong the more it is diluted. As a drink mixer, it may be combined with an alcoholic beverage to prepare a cocktail. Citrus fruits (particularly orange, lime and lemon) or a blend of fruits and berries are commonly used as the base of squash.
