I recommend you contact our hotline experts to get the quickest response. The toll-free hotline (800-354-7319) is open Monday through Friday, 9 a.m. to 4 p.m. (July 15th - October 18th). Extension certified Master Food Preserver volunteers from Lane and Douglas counties take the calls.
Oregon State University Extension Service offers this food preservation and safety hotline every year during the peak canning season. The hotline is available for queries on proper canning techniques, safe recipes to follow, and the locations for pressure canner gauge testing in your area.
Thank you for contacting Ask an Expert, and happy canning!
