I moved to Maryland in July from New York State. Though the move is fairly short – about 200 miles or 360 kilometers – my new home state does have a slightly different climate from New York. This difference does have some nice benefits, like the persimmon trees in my neighbor’s yards, or the slightly warmer winter. However, this also affects food storage. Maryland is just enough more humid and just enough balmier that food lasts for different lengths here. I have to be particularly more careful about flour and rice storage, and things like cake and bread do not stay fresh for quite as long as in New York. The difference is about a day.
So I need to add something quickly to my pantry guide: the fact that you need to take climate into account. Humidity, heat, and temperature changes will make some foods go off more quickly – and may necessitate different storage techniques. For example, in a hot, humid climate, tomatoes will last much longer in the refrigerator – and will go off more quickly when stored at “room temperature.” (Yes, this will affect the taste slightly.) Flour, rice, and noodles will need to be very carefully sealed to prevent bugs from getting in. On the other hand, in a cool, dry climate, it is important to make sure that your containers are fully closed – especially for things like bread, which can go stale quickly.
This knowledge can seem overwhelming. So I recommend: ask around with your local friends and see what they do! No doubt some people will have tips and tricks relevant for you. One example is that I’ve learned many people here keep their flour in the freezer, because Maryland has a particularly big population of flour mites (which are not nice).
Climate change will affect this. As climactic conditions become warmer, more humid or more dry, and with more extreme weather, food is affected in more ways than growing. One thing that has been less discussed is how storing food may need to change – and, if more refrigeration is needed, the resultant energy use and carbon emissions. On a macro level, that could be a big impact. On a micro level, it means that you may end up changing what you consume and how much as the impacts of climate change continue to play out.
Budget accordingly, buy accordingly, and store accordingly! Use tips and tricks for your climate to store things and to make sure things stay yummy and good to eat. Keep an eye out, especially given that extreme weather is sadly here to stay.
