Well ,we will have to adapt . Think about any of this as you would the home front in WW2 , with rationing . You will be ok . If you get a chance , read some of the old cook books , put out by the government , about how to stretch the ration , and substitutions . Interesting reading . You will find far more British books than American , simply because our rationing didnt last all that long , whereas theirs lasted the entire war .
