Evaporation fridge

Sometimes you just don’t have room in your fridge for a huge bowl of dough, starter, leaven, whatever else you have over-bought which is festering in there.

There’s a temorary solution.  You become a smug scientist for the day. Holly Goodhead if you will.  “Recipe” wise, you will need:

plastic box with a tight lid which your bowl (or whatever) will fit into
double bed sheet
bucket
water
a clothes peg or similar

What you do:

Put your bowl, covered in cling film in the box.  Soak the bed sheet in the bath until its wet through.  Wrap the box with the bed sheet leaving a corner hanging out somewhere. Twist it up to make a wick-like end. Put on the clothes peg to stop it unravelling.

Put the sheet covered box in a windy place. A balcony, garden table, doesn’t matter as long as there is some wind passing over it.

Fill the bucket with water and stand it next to the box.  Stick the “wick” end in the bucket.  The wind causes evaporation of the water contained in the sheet, this “pulls” heat from the box and it cools. The bucket of water and the wick keeps the sheet wet.

Wallah*! You now have your own evaporation fridge, and are the envy of all your friends.  It’ll keep your dough cool even on hot days, as long as there is wind passing over it. The stronger the wind the cooler the box and its contents become.

* It’s voila of course. I just like Wallah.

  1. Very clever, is it fox proof?
    Possibly easier to clear the fridge….*hmmm ponders*

    • If your lid is tight (big tupperware lockbox?) then I’m sure it would be. Your neighbours might think you’re cooking up TNT but don’t worry yourself with that.
