Gas-saving scooters! Backyard vacations! Celebrity twins!

Okay, so you can't attribute all trends to a poor economy. Still, a recent run on "canning recipes" may indicate yet another resurgence of a frugal tradition. Summer interest in saving goodies for later has swelled 28% compared to last year. Even more startling, Web queries on anything canning-related is 16 times higher than in 2006.

An AP report credits the canning comeback to produce costs, baby boomers getting earthy, and the local foods movement. Likely, jitters over recalled foods and salmonella tainted peppers probably have also sent people fleeing to their own backyard to salvage safe grub.

Luckily, people have been doing the right things to avoid botulism, looking for "canning jars" of both the Mason and Ball variety. One Scranton, Penn., paper warns that there's "no substitute for adequate heat treatment"—either a boiling water bath or pressure canning.

Top canning ingredient? Tomatoes. That fruit disguised as a vegetable suffered a bruising blow after being falsely fingered for salmonella poisoning, but now cooks want to stock up on the plant, juice, sauce, and salsa variations. Author Barbara Kingsolver rapturously devoted a chapter to the time her family preserved 302 pounds of the red stuff in her newest book.

Whether or not home canners will save money in the long run is up for debate: A McClatchy Newspapers article says the savings usually comes from preserving your own garden bounty, not market-bought goods.
