Day 88: Today's Pick — The Tunnock's Caramel Wafer

I want to write today about a small, modest, perfect chocolate biscuit.

The Tunnock's Caramel Wafer comes in a red-and-gold foil wrapper, slightly old-fashioned, the kind of foil where the gold reads as a 1952 idea of what gold should look like. The biscuit inside is a stack — five thin wafer layers, four layers of soft caramel pasted between them — coated all the way around with milk chocolate. It is roughly the size of two stacked decks of playing cards. It costs, in a UK supermarket, about 35p. In a 30-pack from a specialty importer in the United States it works out to about a dollar each. By any measure, it is not expensive.

It is also, to my mind, one of the most quietly perfect food objects ever produced.

A small bit of history. Tunnock's is a family-owned bakery in Uddingston, just outside Glasgow. They have been making things since 1890. The Caramel Wafer specifically was introduced in 1952, in postwar austerity Britain, and they have made it — in the same recipe, the same wrapper, the same foil, the same machinery in many cases — every day since. The factory floor in Uddingston employs hundreds of people. The biscuits travel by the millions to almost every Scottish corner shop, and from there, by post and suitcase and shoulder bag, to the rest of the world.

Scottish people of a certain age will tell you that there are some childhood foods that you do not so much eat as time-travel into. The Caramel Wafer is one of those. The first bite — the snap of the chocolate, the crunch of the wafer, the slow give of the caramel against your molars — produces, for anyone who grew up with a Tunnock's wrapper in a school packed lunch, a near-pavlovian sensation of being seven years old and slightly bored on a rainy bus. I have watched grown adults take a bite, close their eyes, and produce a noise. The noise is involuntary.

A few practical and important notes if you are not Scottish.

First: do not refrigerate them. The caramel firms into something less pleasant, and the chocolate dulls. Keep them at room temperature. Eat them within a few months of purchase; they are not designed for the long haul.

Second: there is, in the Scottish context, a small ongoing argument about whether the Caramel Wafer is the primary Tunnock's biscuit, or whether that title belongs to the Tea Cake — a domed, chocolate-covered marshmallow biscuit on a small biscuit base, also wrapped in red-and-silver foil, and beloved chiefly because the foil unwraps in a satisfying spiral. Reasonable people disagree. My position: the Tea Cake is the more dramatic biscuit; the Caramel Wafer is the better everyday biscuit. The Tea Cake is for parties. The Caramel Wafer is for Tuesday.

Third: pair it with tea. Strong, milky, hot. The Tunnock's is engineered for tea. The caramel softens slightly against the heat through the wrapper if you let it sit for a minute on the saucer. The wafer holds up to a brief dunk if you are brave. The chocolate does not melt onto your fingers. It is a perfect tea snack and an only-okay coffee snack; this is a feature, not a bug.

Fourth: if you are buying these in the United States or anywhere outside the UK and you find yourself charmed, watch out for two related Tunnock's products: the Snowball (a coconut-coated marshmallow, divisive but excellent) and the plain Wafer (without caramel, hard to find, oddly perfect). The full Tunnock's lineup is a small rabbit hole.

A final, slightly sentimental thought. The Caramel Wafer has not changed since 1952. The packaging has not been redesigned. The recipe has not been "reformulated for the modern palate." There has been no attempt to make it square, or organic, or "premium." It just is what it is, and what it is is good. There are not many objects left in the world like that. When you find one — keep buying it.

This has been Day 88. The Caramel Wafer is the pick. Multipacks are an act of self-care.
