Twix Multipack Chocolate Biscuit & Caramel Bars: The Tea-Break Bar, in summary: Biscuit, caramel, chocolate, in that order. Nine wrapped 20g bars make a cupboard supply rather than a single treat; keep them cool, skip the dunk and pour a brisk, milky breakfast tea or a short black coffee.

Twix was invented at the Mars factory in Slough in 1967 and was on sale in Britain the same year. Almost everything worth knowing about it, from how to store it to what belongs in the mug beside it, follows from the biscuit sitting at its base.

Snap, chew, fade: how the bar is layered

Each bar is three separate layers stacked rather than mixed. At the bottom sits a firm shortcake biscuit, which gives the bar its shape and supplies the only dry note in it. A strip of soft caramel runs along the top of that, and milk chocolate covers everything. Because each layer keeps its own texture, a bite always goes in the same order: the coating gives, the biscuit snaps, then the caramel stretches and lingers.

The caramel is what makes a Twix eat slowly, and it is sweet from every angle, so the biscuit matters more than it looks. It is the one element stopping the bar from being sugar on sugar. That is also why a warm room spoils it: the caramel softens into the crumb, the dry contrast disappears and the whole thing turns flat. Mars sold the same bar across mainland Europe for years as Raider before the Twix name arrived there too.

Why nine wrapped bars, not one big one

This box holds nine individually wrapped bars of 20g each, 180g in all. They are the smaller multipack bars rather than the full-size bar you would pick up singly at a counter, so expect something lighter than the one you might picture. The separate wrappers are the point of the format: one bar can go into a lunchbox, a bag or a coat pocket while the rest of the box stays sealed in the cupboard.

That changes how the box gets used. Nine bars suit one person's afternoons across a week, or a household where everyone takes one, far better than a plate set out for guests. They keep for days rather than an evening, because nothing is opened until it is wanted. Think of the box as a tin by the kettle rather than a single treat.

Chilled, never dunked, and a brisk cup beside it

Temperature matters more with a Twix than with most biscuits, because two of its three layers react to it. Around fifteen minutes somewhere cool firms the caramel so it springs back, and lets the chocolate break cleanly instead of smearing onto your fingers. Freezing goes further and turns the bar into something you crunch rather than chew; opinion divides sharply on that, so try a single bar before committing the whole box.

Keep it out of the mug. Dunked, the chocolate slides off into the tea and the caramel goes limp and stringy, so reach for a digestive or a Hobnob when dunking is the aim. What a Twix does want is a cup with enough grip to cut through caramel and chocolate: a strong breakfast blend or an Assam with milk, or a black coffee. Delicate teas such as a Darjeeling or a jasmine green simply get lost beside it.

FAQ

How many bars are in a Twix multipack? Nine, each weighing 20g, for 180g in the box. Every bar is wrapped separately.

Can you dunk a Twix? Not successfully. The chocolate melts into the tea and the caramel goes soft and stringy, so eat it beside the cup.

Should Twix go in the fridge? A short spell is worth it: about fifteen minutes cool firms the caramel and gives the chocolate a clean break. Freezing makes it crunchy, which some people love and others do not.

What allergens does Twix contain? Mars lists wheat (gluten), milk and soya, with a may-contain warning for hazelnut, almond and gluten from barley and oats. Always check the current pack.

Where was Twix invented? At the Mars factory in Slough in 1967, the same site where the Mars bar was created in 1932.

Curator's note: Fifteen minutes in the fridge, a proper strong mug beside it, and one bar is plenty. Leave the box by a radiator and you are eating a different, lesser thing. Lee, teas.co.uk, Tunbridge Wells.
