Preparation

Do you remember the first thermos you ever used? Was it for the soup that was a regular part of the lunch you took to school? By now you know that thermoses can be used for more than just soup. Thanks to vacuum insulated technology, they can keep wine cool on a hot summer day or hold tea that pours out still steaming on a crisp fall morning.

Though most of us use a thermos for a favorite drink, there’s more you can do with them than that. Divya Alter, founder of Ayurvedic food brand Divya’s, uses thermoses to keep home cooked breakfasts and lunches hot and temperature safe for work or travel days. She also cooks food inside thermoses using boiling water and allowing whatever is inside to slow cook. “At home, I use a beverage thermos with hot tea or water in the winter or when I’m not feeling well,” she adds.

When shopping for a thermos, Kaleena Teoh, co-owner of Coffee Project New York, looks at the product specs to see how long it can hold temperature. Since she mostly uses thermoses to hold liquids like coffee and tea, being able to enjoy her favorite beverages throughout the day at optimal temperature is key. Size is another important consideration. “I have thermoses of different sizes that I use to carry different drinks,” she says. One last thing to note is that while most thermoses can be used for hot and cold food and drinks, not all can. So if you’re planning on pouring both hot and cold things into a thermos, make sure it’s manufactured to do so.
