Well I'm not sure it's a good thing to have to be prepared, but yes I do think that we have all got soft about storecupboard ingredients.
Personally, I don't have space in my freezer to freeze milk (keep powdered for dire emergencies) but I do have a storecupboard we could live off for quite a while. Also always keep ingredients for a meal cookable in the dark by campstove (bottle sausages, potato rosti in a packet and tinned fruit if you're interested)
We store lots of veg, tinned pulses, powdered milk, flour, eggs etc. We are quite prepared. I have a lovely lentil bolognese recipe that uses store cupboard ingredients. I could post it here if anybodys interested.
We have lots of dry goods and tinned goods. If the weather is very bad and the electricity goes off then we have our camping stove (2burners and a grill) plus Calor gas. And in the house we have a wood/coal burner and lots and lots of wood that we collect over the summer and dry in the shed for winter (collected from skips and driftwood).
We have to be prepared as we live 10 miles away from any supermarkets. Ok have a village shop but it's pretty basic.
Not necessarily prepared but less dependant on supermarkets for every little thing. I tried to grow veggies this year and despite only managing one tomato (which i don't even like!) I was over joyed! Not only does it make you realise just how much work goes into growing what we eat, it made me more determined to at least provide a little bit for my family.
