Not so much on the perishables but more store cupboard staples and being more efficient with buying/freezing food.
I've started freezing milk which is a great back-up.
I purchased plenty of flours etc so I can bake more and can easily bake my own bread too.
Does this not teach us to prepare better in November? Because of all these mild winters we have all become a little lax with planning for the worst.
Surely this is a good thing?
