In
some ways, the story of future food is of prediction running so close
on the heels of progress that they tend to fall over one another with
tedious regularity.
Take the case of food packaging. The idea of a complete
pre-packaged meal that doesn't need any preparation is a perfect
artefact of the ideal world of tomorrow, but no sooner did the pundits
start to wrap their minds around the concept in the '50s than the
Swanson people took several thousand surplus turkeys and turned them
into the world's first TV dinners.
In fact, the very term "TV dinner" was coined to point up the
futuristic idea of a complete meal that you just heat and eat.
Contrary to popular belief, TV dinner had nothing to do with munching
on rubber chicken in front of the goggle box. In '50s America,
television was the symbol of modernity and what could make this Ur
convenience food seem like the meal of tomorrow better than latching
the letters TV to it. If it had been invented twenty years
earlier they'd have called them Radio Dinners.
But pre-packed meals were only half of the equation. What really
made the Buck Rogers school of food take off was the microwave oven.
Now you not only had the meal, you didn't even have to hang about
while it heated up. Just stick it in the box, push a button, and let
the electrons do the work in seconds.
This wasn't cooking, it was nuking and it worked so
well that the automatic kitchen so often predicted became redundant.
Why build a machine to cook for you when you can buy your dinner ready
made and zap it in thirty seconds?

Amazingly,
this didn't just drop out of the blue after the Second World War.
Back in the 1930s, Hugo Gernsback's magazines were
toying with cooking with radio
waves, though in a fashion that was even more rough and ready than
the early microwave model featured above.
One prediction that
did come true, though with remarkable slowness was the self-heating
can. It seems that every ten years or so someone again says that
it would be great if someone makes a can that could heat itself up
when you opened it and shortly thereafter someone claims to have
perfected it. It was such a regular item on the grocery list of
the future that Heinlein was writing about them in his juvenile novels
in the '50s.
Trouble is, the self-heating can is one of those things that is
easy in theory and hard in practice. Basically all you
need to make such a can is a compartment filled with slaked lime that
you add water to at the appropriate moment. The water and the
lime interact, you get an exothermic reaction and voila!
You have a hot meal. Thing is, you've got to get the chemicals
to mix just right or you either get lukewarm chicken soup or your pork
and beans becomes a neat little hand grenade.
Thanks to decades of tinkering, and a big push from the military who
regard self-heating food as a real plus for the infantry, the
self-heating can is now a reality–though incredibly pricey compared
to their non-heating cousins.
And the sausages still need some work. |
