I've thought about starting a topic on home canning, but there are so many books on the subject that I figured it would be a waste of time. The major expense is in buying the jars, but you make that up in a season or two.
The same with sprouting. There are tons of books on how to grow sprouts, and I'm surprised more people don't do it. A few radish sprouts will add some zest to any bean or chili dish. But use them in moderation, they're hot.
Alfalfa sprouts make a great salad. And I add bean sprouts to sandwiches and burgers. If you know a farmer who's letting a few acres of alfalfa go to seed, definitely talk to him.
