You just got to have a biccy with your cuppa. It just makes it taste better, doesn’t it? Both the biscuit and the tea. Did you know though, that there’s quite some history behind why we are dunking our crumbly goodnesses into our brews?
A brief history of dunking
Biscuits arrived in Britain long before anyone thought to lower them into a cup, of course. But early versions of the deliciousness we know today were closer to hardtack than Hobnobs: dry, durable, and designed to last rather than to actually please. Tea, meanwhile, filtered down from the elite in the 17th century, becoming a daily staple by the Victorian era. Put the two together and practicality took over. Dunking softened what teeth struggled with and made modest ingredients feel quite indulgent.
By the 19th century, tea tables were social stages and biscuits were baked to be sturdy enough for handling but still brittle, and dunking became an unspoken skill. Too long and you lost half of it to the cup. Too quick and you gained nothing! George Orwell later had strong opinions on the subject, while everyday etiquette guides simply assumed everyone did it, even if no one said so outright. What started as a solution to dryness had quite successfully settled into a ritual.
The perfect dunk
There’s a reason dunking feels so satisfying. When a biscuit hits hot tea, capillary action takes over. Liquid races into tiny air pockets, softening the structure from the inside out. Sugars dissolve, fats warm up, and aromas lift. For a brief window, you get a yielding centre with just enough edge to hold its shape. Miss that window and the whole thing collapses, usually at the most inconvenient moment.
Food scientists have had a quiet chuckle over this. Informal studies and a willingness to sacrifice biscuits for knowledge show that texture matters more than flavour at the point of dunking. Porosity, fat content, and thickness decide whether a biscuit survives. That’s why classics like shortbread biscuits, digestives or bourbons with their crumbly richness and high butter content behave so beautifully (when handled with care).
Tea plays its part too. Hotter liquid speeds absorption, while milk changes the surface tension, subtly altering how fast the biscuit drinks. Even the angle matters. A shallow dip lets you control the soak; a full plunge is for the bold or the reckless. All of this happens in seconds, but it’s enough to turn a plain snack into something rounded and comforting. Science, it turns out, is very much on the side of the dunk.
Still going strong
Despite changing tastes and busier lives, dunking hasn’t gone anywhere. If anything, it’s adapted. The biscuits might be gluten-free, vegan, or wrapped in minimalist packaging, but the motion is the same. Dip, pause, lift. Hope. Younger generations haven’t rejected it so much as reframed it and social media is full of slow-motion dunks and playful rankings.
So there we go – here’s why we dunk our biscuits. And now, if you’ll excuse me, I have a kettle to pop on.
