Picking Wild Crowberries in Iceland

Fantastic day today picking berries in Reykjavik, Iceland. I picked my people up in Reykjavik's centre and then we drove for maybe 30 minutes. You don't have to go so far to get into the nature in Iceland, Reykjavik is a small city with nice lands for picking berries!
We mainly picked Crowberries which is the most common type of berries in the Icelandic nature but we also picked some Bilberries (what we call blueberries). I had been baking some muffins yesterday and I took some with me to give a taste on the tour and show what you can do with the berries. In the end everyone got some recipes.
This is the muffin recipe:

270g sugar
150g butter
2 eggs
240g flour
1/2 tsp baking powder
50ml milk
1 tsp vanilla
Crowberries or Blueberries
80g Cocoanut flings

Preheat the oven to 170°C. Whip butter and sugar until it is light yellow and very easy to whip. Put one egg in and whip. Put another egg and whip. Put the flour, baking powder and the flings into the bowl, milk and the vanilla and stir. Divide the dough into the cups and put some flings over and put some berries over. Bake the muffins for 16-18 minutes.
