Bush Brothers & Company had been canning a variety of fruits and vegetables for over 60 years when, in 1969, the company created canned baked beans using a cherished recipe from a family matriarch. Sales jumped from 10 thousand cases in the first year to over 100 thousand cases in 1970. And just one year later sales hit a million cases. Today Bush’s makes over 80 percent of the canned baked beans sold in the U.S., and the secret family recipe remains a top food secret, despite Duke’s attempts. A replica of the original recipe book—without the original recipe in it (drat!)—is on display at the company's visitor center in Chestnut Hill, Tennessee.
