Canning and Food Preservation Resources

Did you know that because Utah's elevation ranges dramatically, canning in our state requires special attention and changes to canning times and pressures?  See the chart below for specific SALT LAKE COUNTY recommendations for high elevations followed by further information and resources. 

Need a Good Salsa Recipe?

We are often asked for a tested and safe salsa recipe that actually tastes good and is not too "vinegarish".  Here are some taste-tester favorites from the Ball Blue Book Guide to Preserving.

Acidification for Tomatoes

To ensure safe acidity in whole, crushed, or juiced tomatoes, add 2 tablespoons of bottled lemon juice or 1/2 teaspoon citric acid per quart of tomatoes.  Acid can be added directly to the jars before filling with product.  Add sugar to offset acid taste, if desired.  Vinegar may also be used;  use 4 tablespoons of 5% acidity vinegar per quart.  However, vinegar may cause undesirable flavor changes.  We recommend the lemon juice or citric acid. 

Steam Canners

The USDA does not recommend the use of steam canners due to inadequate research and testing.  However, Utah State University tested the steam canners and found them to be safe and adequate for processing certain goods, if used according to instructions and safe canning procedures.  Due to botulism poisoning potential, we DO NOT recommend that you use a seam canner for meat, tomatoes, and vegetables.  If you choose to use a steam canner for fruits, jams, and jellies, only USDA approved and tested recipes and canning times should be used.  Processing times for boiling-waterbath canners may be used for the steam canners.  It is very important to make sure that an eight inch plume of steam is present during the entire processing and water must not run out before the end of processing.
