From sardine popcorn to yeast and ketchup: history's strangest sandwiches

Although the sandwich is an outwardly ordinary food, it has taken unexpected forms throughout its history. Writing for HistoryExtra, Jonny Wilkes brings together the strangest sandwich fillings tried in the past, shedding light on an unusual corner of food history.

Among the examples Wilkes compiles for HistoryExtra are surprising combinations such as the sardine-laced popcorn featured in the headline. Pairings like these, while hard to reconcile with today's palate, reflect the ingredient availability and sense of taste of their own eras.

Another striking example on the list is a filling made from a mixture of yeast and ketchup. This recipe, as Wilkes relates, shows that the sandwich can be not merely a meal but also a mirror of cultural and economic conditions.

For food historians, examples of this kind carry valuable clues about everyday life in the past. Which ingredients were cheap, available or fashionable also tells us about a society's culinary habits and, indirectly, its economic situation.

The origin of the sandwich rests on a popular narrative most often associated with 18th-century England; yet the idea of putting something between two slices of bread reaches back much further. The historical view Wilkes frames underlines how flexible this simple form is.

There may be practical reasons behind some of the strange recipes. Times of scarcity, wartime rations or an abundance of particular ingredients may have made combinations that look odd today perfectly sensible in their own context.

Wilkes's piece approaches these examples not in a judgemental tone but with a sense of curiosity and humour. The phrase 'enjoyed or endured' also serves as a reminder that the food experiences of the past were not always pleasant.

Food history is a field that has increasingly drawn academic and popular interest in recent years. Studying everyday objects and habits opens a rich window onto the lives of ordinary people, who are often overshadowed by major political events.

Compilations of this kind also serve to make history accessible. Looking at the past through a familiar food makes it easier for readers to connect with their own culinary experiences and to reawaken their historical curiosity.

In the end, Wilkes's piece for HistoryExtra shows that even a humble food like the sandwich can hold a rich historical narrative. The strange fillings offer a fun but informative look at the tastes, constraints and creativity of the past.
