Hi Linda,

Welcome to the concession business. Most people plan the end of the day and will shut down the friers before they actually close-up on the last day. If you are buying shortening or oil in heavy plastic containers, they have a high melting point, you can check by placing boiling water in one and seeing what happens. That means it will hold at least 212 degree oil.

Thanks for posting, I hope you will join the community.
