The machinery that snack and cereal companies use to transform rice and other foods into puffed snacks is expensive and operates at extreme pressures and temperatures. Since you can buy the resulting cheese puffs, rice cakes and toasty oat cereals anywhere, why try to make them ourselves? Because we were curious whether we could figure out a cheap way to crack the code of puffing technology. Plus, we like to build elaborate machines and to blow things up, even if it’s only spelt grains and millet cakes.
The grain crops that we humans depend on daily to hold body and soul together are annual crops -- they have to be planted every year. They germinate, bear their delicious product, and then die off; the following year, a brand new crop is put in to take their place.
Such annual crops are high in yield, but they require vast amounts of artificial fertilizer, and their impermanence contributes to soil erosion.
