NPR:
Call it a reaction to high food prices, food recalls, and a bad economy. Or just call it retro chic. But there’s no doubt canning is newly trendy among people who a couple of years ago probably didn’t give much thought to what goes into a jar.
According to a recent survey by Opinion Research, 43 percent of consumers interested in canning are ages 18-34. And since 2009, searches for “canning recipes” on allrecipes.com has increased 61 percent during the summer months, says Judith Dern of the popular website.
