My sardines might last you a century and your tomato purée would last me even longer.
The sort of items you keep in hand and their degree of antiquity will tell a lot about you. Sad tubs of largely unused Thai green curry mix or packs of ras el hanout that went out of date a year or so back highlight the adventures into cooking that didn’t work for you. Jars of peaches in brandy or homemade chutneys and pickles that came as gifts and that you have forgotten to repackage and give to someone else.
