I’m normally impatient, but it gets worse when I’m hungry.
Today’s invention is a way to cook things faster on a gas hob.
It’s very common to have a kitchen cooker with four gas rings arrayed in a square. Imagine having a device consisting of three linked pipes (light grey). This can be placed on top of the four burners so as to direct the flow of gas from all four to the single lit one.
This allows a fourfold increase in heat transfer to the pot you want to boil first (or, using a pressure cooker, the pot you want to heat most intensely).
The unit can of course be repositioned to direct the extra heat to any one of the four burner locations.
