Sometimes, just do something random. And it doesn’t come much more random than Icelandic cookies.
I have no connection to Iceland, and have never been. However, it does intrigue me. I would dearly love to visit the Blue Lagoon geothermal spa at some point in the near future and spend some time walking across the lunar-like landscapes. I was also vaguely affected when the Eyjafjallajökull volcano that brought European air travel to a standstill last year. But…that’s it. Being honest, I’m not sure I’ve ever even eaten anything Icelandic.
Nevertheless I read about these air cookies and it struck me as a bit of fun. So here we go – my tenth Christmas bakes post!
The point of these cookies is exactly as their name suggests – they should be light, light, light. They are a doddle to make – icing sugar, cocoa powder and egg. But the magic is the raising agent – ammonium carbonate – which means they puff up spectacularly. As you can see – a six-fold increase in volume!
You can see above the traditional way to make them – use a biscuit press with a ridged attachment, then cut into individual pieces about 5cm (2 inches) long.
Then I put them in the oven…and boy did they rise! What was less exciting and, frankly, rather alarming was the fact once they were done, I almost managed to gas myself on ammonia fumes.
OK, somewhat of an exaggeration, but there was certainly a pong that filled the house, and I am very, very glad I attempted this on a sunny but breezy winter morning. The doors could be opened, and the stink was dispersed relatively quickly. I knew this stink-fest was on the way from when I made Swedish drömmar biscuits but even when you know it is coming, the sheer impact of the smell never fails to surprise.
Anyway, with the drama of the mystery smell overcome, and the house once again fresh-smelling (i.e. not of ammonia), the cookies were ready. They look good and, given the earlier smelly experience, they don’t stink. That’s what I want in a biscuit – one that doesn’t make the eyes water! The cookies are crisp and like a little like dry meringue, but not quite the same texture. But fun. They are also hollow in the middle, so they are indeed light as a feather!
The “ridged” look is traditional, but if you don’t have a biscuit press to hand, then fret not! A little online research revealed that you can also make other shapes, and I was very taken with this idea of straws – I tried it, and the result was great – I still got “lift off” and the resulting straws were light and crisp
I’ve written a little bit about the history of ammonium carbonate before (here). It’s funny stuff, but if possible it’s worth getting hold of it – in fact, if you want to make these air cookies, you must have ammonium carbonate to make them work. Nothing, but nothing, will work in its place!
So try them – and good luck! Or gangi þér vel as they (apparently) say in Reykjavik. But of course, I’ll need to visit to be sure!
To make Loftkökur:
• 300g icing sugar
• 1 teaspoon baker’s ammonia (ammonium carbonate)
• 2 1/2 tablespoons (30g) cocoa powder
• 1 egg, beaten
Preheat the oven to 150°C. Lightly grease a non-stick baking tray.
Mix the icing sugar, baker’s ammonia and cocoa powder in a bowl. Add the egg and mix well. Use a spoon at first, but you’ll need to use your hands to get the dough to come together. It will be quite stiff.
To shape the cookies, you have two choices: (1) put the mixture into a cookie press and press. Hey presto, the dough comes out. Cut the resulting strip into pieces – aim for cookies about 5cm (2 inches) long; or (2) roll into very long, thin “sticks” of dough.
Bake the loftkökur for 10 minutes – watch them puff up, but be careful of the fumes when you open the oven door.
To get ammonium carbonate in London, you can buy this from Scandinavian Kitchen in the city centre (61 Great Titchfield Street, London W1W 7PP), tel: 020 7580 7161. Tube: Oxford Circus.
Worth making? Loftkökur are worth trying for the novelty factor alone! Normal chocolate meringue is a bit easier on the nose, but if you’re looking for something quick and easy to do with kids (who will screech with delight when the pong makes itself known), then this might just do the trick. Just make sure it’s a nice day, and there is plenty of wind outside so you can air the kitchen out as necessary
