- Typically burns for about 2 hours per can
These characteristics make Sterno ideal for various practical uses, from heating food to emergency cooking during power outages.
Primary Uses of Sterno
1. Keeping Food Warm at Events
One of the most common uses for Sterno is in the food service industry, where it’s used to keep dishes warm during catering or buffet setups. Chafing dishes are designed to hold trays of food above a Sterno can placed underneath in a holder. The gentle, steady heat provided by the Sterno keeps food at safe serving temperatures without overcooking it or drying it out.
Popular for weddings, banquets, corporate events, and family gatherings, Sterno allows caterers to serve meals efficiently while maintaining food safety standards. It’s especially useful in locations without access to kitchen equipment or electricity.
2. Camping and Outdoor Cooking
For campers and outdoor enthusiasts, Sterno offers a lightweight and convenient fuel source. While it’s not designed for full meal preparation like a propane stove, it’s perfect for heating canned food, boiling water, or making simple meals like instant noodles or oatmeal. Many portable cooking kits come with stands that accommodate Sterno cans, providing a compact setup that’s easy to carry and use in the wilderness.
3. Emergency Preparedness
In power outages or natural disasters, Sterno can be a lifesaver. Its long shelf life and ease of use make it an ideal addition to emergency kits. It can be used to boil water for drinking, heat meals, or even warm up a small area. Because it doesn’t require electricity or batteries, Sterno is a dependable source of heat when other options are unavailable.
4. Fondue and Tabletop Cooking
Sterno is also used for fondue pots and tabletop grills in home dining or restaurants. The controlled flame is gentle enough to melt cheese or chocolate without scorching, and it creates a cozy atmosphere for interactive meals. Many fondue sets are designed specifically to use Sterno-style fuel cans, allowing guests to cook or dip ingredients right at the table.
5. Science Demonstrations and Educational Use
In educational settings, Sterno can be used for demonstrations that require an open flame or heat source. Whether it’s melting substances, demonstrating thermal energy, or showing chemical reactions, Sterno provides a safe and stable flame that can be used under supervision in classrooms or laboratories.
