Still a couple of weeks to go before we get into prime solar cooking season here, as calculated by my Dad, but it was a beautiful day today, so we thought - why don't we have a go at something that only needs a short amount of cooking?
Boiled eggs it was.
We started at around 10.30am. We put the eggs in our black pot and covered them with warm water from the tap. I know warm water was slightly cheating, but I was desperately trying to maximise our chances of success, given that it's so early in the season, and the sun is still relatively low in the sky.
We put the pot in the cooker on two stacked cake racks to raise it up slightly and make sure the underside of the pot could heat up properly. (We had problems last summer with our panel cooker when we didn't raise the pot.)
We closed the lid, angled it towards the sun, and left it for a bit. At this point I learned my first lesson of the season: Make sure the outside of your pot is absolutely dry when you put it in the cooker!
I had given the pot a quick wash before we used it, and hadn't dried it properly. After it had been in the cooker for about half an hour it started to steam up the window. We had to open it all up again, wipe down the window, dry the outside of the pot, and then start again.
We left the eggs cooking there till about 3.30pm ... or maybe it was 4.30. I'm a bit confused by daylight saving.
During that time we moved the cooker about three times to follow the sun. As you can see from the pic below, by the end of that time it was practically falling off the deck. (And so was the cat.)
We opened the pot nervously. The water wasn't boiling, but a promising cloud of steam billowed out ...
My son did the honours with the first egg. The white was cooked.
And so was the yolk!
Hurray! Our box cooker works!
