Should I pre-warm my food Jar?

We recommend pre-warming your Food Jar,  just prior to use with boiling water. Rest the lid on top of the jar and let stand for 10 minutes, then empty.

After pre-warming, fill your food jar and attach the lid for maximum insulation efficiency

Keep lid in place as much as possible to keep your food warm.

WARNING: Always exercise caution with hot foods to avoid burns and scalds.
