Daily Kitchen Note
Waiting for a large pot of water to boil on the stove can be time-consuming and energy-intensive. By using an electric kettle to bring the water to a boil first, you can significantly cut down on prep time and save energy.
How to Preheat water
- Fill your electric kettle with the amount of water needed for your recipe.
- Turn on the electric kettle and bring the water to a full boil.
- While the kettle is heating, place your cooking pot on the stove and turn the burner to medium-high heat to preheat the pot.
- Carefully pour the boiling water from the kettle into the preheated pot.
- Turn the burner to high to quickly return the water to a rolling boil, then proceed with cooking your pasta, grains, or vegetables.
Why it works
Electric kettles are designed with heating elements that sit directly in the water and are well insulated, making them about 80 percent efficient at transferring heat compared to the roughly 70 percent efficiency of an electric stovetop. This direct heat transfer brings water to a boil much faster and with less energy loss to the surrounding air.
