Pasta giant Barilla recommends passive cooking of pasta. Passive in the sense that it utilizes the residual heat after a period of cooking, rather than active heating, which involves keeping the heat on the entire time the pasta is being cooked. To this end, Barilla has released a device called the Passive Cooker and a dedicated mobile app to help you cook passively.

Here‘s how it works. You place the Passive Cooker on the lid of a pot, and the device notifies you via the app when the water is boiling. This means it‘s time to add the pasta to the water. After two minutes, the app will notify you again to let you know it‘s time to turn off the heat. After two minutes of active heating, it‘s time for passive residual heat. The residual heat from the boiling water will finish cooking the pasta. At this point, the passive cooker on the lid of the pot will detect the residual heat and let you know how long it will take for the pasta to be fully cooked, again via the app.

In fact, there‘s not much difference between the normal cooking time and the passive cooking time. If you‘re cooking macaroni, for example, it takes 7 minutes to cook conventionally, but with passive cooking it takes 2+6 minutes, or only 1 minute more. Instead, you only need to turn on the stove for two minutes, which means your gas or electricity bill will be much lower, and your carbon footprint will be reduced by up to 80%, says Barilla.

Barilla has open-sourced the manufacturing information for the Passive Cooker, which will notify you when it‘s time to passively cook. The 3D printed case, printed with 100% biodegradable filament, houses two AAA batteries, a temperature sensor, and an Arduino board. Barilla has made the device‘s open source files and instructions available for download on its website. However, if you don‘t want to build your own passive cooker, Barilla offers a chatbot via WhatsApp. It guides you step-by-step on how to passively cook pasta.
