The ptarmigan is a popular Christmas dish in Iceland, but I'm not waiting that long. This one's gonna be ready in about 15 minutes. Mmm. Look at that -- all that dark meat. Quite strong. 

Here's an angelica plant. There are very special plants in Iceland. They actually grow wild all over the place. But you can recognize these in the summertime. All of this is green, and they have these white flowers on the top. Now, obviously, in the wintertime, it's bare, but you can see its very distinct shape. But what I'm after is the roots. And actually, all of these roots are edible for food if I scrape away a bit of the sand here to get to the inside of the root there. This is all edible, and actually it's gonna make my mouth also a little bit numb because it's actually a local anesthetic as well. But it's good for me. It's gonna boost my immune system, this stuff. And actually it's also antibacterial, so what I can also do is take a bit of it and, like, clean my teeth with it, which is always nice when you're out in the wilds with no toothbrush. When you're stranded in the wilds, it's still important to try and look after yourself.

Here is one of the many ancient lava fields that covers over 10% of Iceland. They're formed by volcanic eruption when the molten rock cools and solidifies, and they can be treacherous to cross. See here, all of these lava fields is just covered in this moss. And it's just making crossing it really slow, slow work. Also, I need to be careful, just because it's hard to tell what the moss is growing over, whether it's, like, a hollow or gap or solid rock. I mean, it’s just too easy to twist an ankle in this stuff.
