Coca-cola light

They are closely related, but their recipes and flavour can differ; the names and formulations also vary between markets. Both are cola drinks sweetened without sugar, so one may taste sharper or sweeter to you than the other.

Many versions contain caffeine, though caffeine-free versions are sold in some markets. Look for “caffeine-free” on the packaging if you want to avoid it.

You can use it to simmer ham, but it will not make the sticky, browned glaze that full-sugar cola does: it lacks the sugar that thickens and caramelises. For a glaze, reduce it with a little sugar or honey and brush it on near the end of cooking.

Refrigerate it with the cap firmly closed and drink it while it is still fizzy. Pour gently and avoid leaving it open, as escaping carbon dioxide quickly makes the drink taste flat.

Its crisp sweetness works well with salty, spicy food such as burgers, pizza, curry and crisps. Serve it cold over ice, or add a wedge of lemon or lime for a sharper finish.

Avoid leaving a sealed can or bottle in the freezer: the liquid expands as it freezes and the container can split or burst. To chill it fast, stand it in a bowl of ice and water instead.
