How Britain coped with the 1976 potato shortage

In the summer of 1976, Britain discovered the limits of its national stoicism. The drought scorched fields, potato yields collapsed, and chip shops quietly began to reduce portions or close early. It wasn’t official rationing, but it certainly felt like it. One woman later said that asking for chips that summer “was like asking for diamonds”.

The AMSR Archive shows exactly how households coped when the most British of foods became scarce. Instant mashed potato – IMP in the language of the reports – moved from cupboard‑back‑up to domestic necessity. A 1981 IMP U&A study notes the turning point plainly: “high sales of IMP due to the drought and poor harvest of 1976.”(1)

The TGI trend data confirms it (6). Usage rose from 35% of housewives in 1975 to 38% in 1976, peaking at 43% in 1977 – the highest figure in the entire 25‑year series. Heavy use rose too. The drought didn’t just drive trial; it changed behaviour.

But the archive also shows the emotional effort behind this shift. In a 1973 study we see that  potato norms were deeply embedded: “Potatoes are part of a proper meal”; “You can’t beat real potatoes”(4).  In a 1975 study women said  “Frozen potatoes are alright in a hurry”; “They’re not the same as proper potatoes”(5) .

For many women at the time, instant mash carried guilt. One respondent admitted, “I always apologise if I produce it” (1).  Another said she felt as if she “hadn’t pulled her weight”(1). |They said things like: “It’s alright for the kids – they don’t notice”, “I keep it in the cupboard for when things go wrong”, “It’s not something you’d give to visitors”,  “It’s handy when you’re caught short”.  Real potatoes were part of the moral architecture of cooking; IMP was a shortcut.

The drought suspended those rules. The U&A report observed that emergencies allowed women to relax the “proper rules of caring, providing and being a woman”(1). In 1976, the ‘emergency’ lasted all summer.

Different groups adapted in different ways. Light users concealed IMP in shepherd’s pie – “the meat underneath is mine” (1) – while heavy users embraced its practicality. One described using it to “contend with the unpredictable”. Younger “modern acceptors” saw it as simply sensible: “Cooking for the family is an old‑fashioned way of expressing love”(1).

And then there was advertising. The Smash Martians campaign, running from 1974 to 1977, met the moment perfectly (7). It made instant mash funny, modern and socially acceptable at precisely the point when households needed permission to use it.

By the early 1980s, usage declined again. The crisis had passed; the guilt returned (but has since dissipated with time); chilled mash arrived. But for one brief period – one drought, one summer, one perfect alignment of necessity and humour – instant mash became part of Britain’s cultural life.

Timing, as the archive shows, was everything. Future comparisons with 2026 will be interesting!
