Warm Soup for Later
Don’t you love the idea of eating hot soup high up on a frigid mountain peak? Me too. The best way to stay warm in the cold is to eat and drink warm food. Usually, someone brings along a flask filled with coffee or warm water for tea. I used to take a flask of coffee to work with me every day, and I would have warm coffee almost all day long. But what about soup?
Will Soup Stay Hot in a Flask?
The short answer. Yes, flasks will keep your soup hot, to an extent.
There are flasks made exclusively for soup (click to view best ones). They have large open mouths, and a big lid that can double as a bowl, and some even have spoons. Flasks are excellent for keeping your soup warm, but like most things, you get what you pay for.
Usually, the lower the quality the flask is, the faster your soup will go cold. An even the best of the flasks can have trouble keeping soup hot for hours on end. Especially when it’s in cold temperatures.
The easiest way to have good hot soup for later is; buy a high-quality flask, prep the flask by filling it with hot water for 10 minutes, and keep the flask in a warm place. With all the right variables, you can have hot soup from a flask for lunch and maybe even dinner.
The Importance of Prepping Your Flask, Thermos, or Food Jar.
No matter what kind of food jar you have for your soup, it needs to be prepped to keep your food hot or cold longer.
For hot food, you prep your food jar by pouring hot or boiling water into it. Let it sit for at least 5 minutes to warm it up properly. When you pour your hot food it the jar is already warm and will not cool the food, and the insulation is heated, so there will be less heat transfer. Meaning your food will stay warm longer.
The same concept works for cold foods or liquids. Prep the container by pouring in cold liquid and letting it sit for at least 5 minutes, or leave the jar in the fridge for a few hours with the lid off.
