As promised..... here is the dumpling recipe we used on our recent camping trip. It's a family favourite of ours and I think the recipe was one my Sister (Kristy's Random Haunt) was taught at school:
1 cup S.R. Flour
30g marg (or 1 dollop in camping measurements)
2-3 tbsp milk
Rub butter into flour then mix in egg and milk with a knife.
