I grew up in a household where the hiss and huff of the pressure cooker was a familiar kitchen melody.
My mother owned a large specimen of what the French commonly call une cocotte minute — this is a brand name to the generic, and less endearing, term autocuiseur — and I seem to remember she used it mostly to boil or steam vegetables, such as potatoes and globe artichokes, or the cauliflower for her gratin de chou-fleur.
I myself went without one for a while, until Maxence’s grandparents had to sell their country house and I was offered a few pieces of cooking equipment, including the jumbo pressure cooker that had served to feed a whole generation of grandkids.
I loved it, but it soon turned out to be too large for me: with a ten-liter capacity, it was both too big for the quantities of food I ordinarily cook, and too bulky to fit in my teeny sink when the time came to wash it up.
And so, trapped between these inconveniences and the sentimental attachment to a family heirloom, I let the poor beast collect dust on a shelf.
Until one day, I decided there was something cosmically wrong about this situation: what I needed was a smaller pressure cooker, and this large pressure cooker was no doubt needed by someone else. Who was I to halt the natural flow of the universe?
Once the decision was made, it was easy: within a month, thanks to a popular auction website, I’d purchased a second-hand, 4.5-liter pressure cooker, and found a happy buyer for my own*.
And why am I drawn to the pressure cooker in the first place, you ask? Well, it is among the most energy-efficient cooking vessels out there, that’s why: as you seal the lid tightly then heat the pot, pressure builds up inside, and this causes the boiling point of water to increase** (from ~100°C to ~120°C, or from ~212°F to ~248°F). In this environment, foods cook considerably faster and with less water than in a regular pot boiling on the stove.
