I was thinking that it would be nice to have a pot that does sous vide for small batches of food.
It would be good for milk, eggs, and more.
The pot would look like a shallow rice cooker or a small steam cooker, except that water goes into the container and temperature control is built in.
This would be basically Precision Cooker integrated with a pot. This would not be steam-based like Precision Oven.
Originally I was looking for something that can be used to heat a few servings of milk while controlling the temperature, so that it does not filament. From searching, the closest machine to what I was looking for was a milk bottle warmer for infants.
One of the benefits of having a pot version is that since it would need less water, it would take less time for heating up water to the target temperature.
