I just got back today from my trip.
For food I tried to go primal.
Grassfed highland cattle alpine salami
And my own home made dehydrated sweet potato - I'm not sure if sweet potato is considered very paleo but I figured it was better than regular potato.
Boil your sweet potato chunks for 10 minutes until soft.
Drain most of the water. Leave a bit
Sorta like mashed/baby food.
Now spread it out on grease proof baking paper very thinly and evenly - sorry I forgot a picture of this so here is a picture of my tomato and normal potato (before I went primal)
Oven should be at about 50-65 Celsius. 8-10 hours.
A sheet - again that is tomato paste - also can be primal and super tasty.
In the field.
Simply rehydrate in the field with some water - leave it, stir it. Then put it on the heat and hey presto!
I also gathered bilberries in the mountains
What I will try next is Pemmican!
