I should point out before starting my list that I carry as standard a HUGE store cupboard. Goes back to the years of being a temp and didn't know how much I would get in any given week. Maybe in another life I was a boy scout!! This is just the basic unopened edible stuff.
Yeah I always have Angel hair pasta or similar, as well as fettucine or tagliatelle, canneloni and lasanga sheets. Oh and a shape like spirals.
Rice, cous cous and corn chips
Canned tomatoes (whole and crushed/peeled), beetroot, pineapple, mushrooms in butter sauce and champignons, tuna, salmon, anchovies, ham, and a dessert fruit
A couple of ready to heat meals like baked beans, steak and kidney pie, that sort of stuff as well as various soups
An oil of some sort
A jam or marmalade and some savoury spread
Jelly crystals
Various sauces like Worcestershire, taco and tomato
Water, long-life fruit juices, and cool drink
Then into the opened stuff, you will always find:
Herbs, spices and other seasonings and sauces, oils and vinegars
Rice, flour and sugars
Powdered drink mixes and cordials, teas and coffees
Now if I was to do a real stocktake and went past my essentials, you may as well all go home and come back another day to see if I had finished yet!! I can go quite a long time without buying anything more than fresh milk, bread and veges!! Oh and please don't ask me about my fridge/freezer contents!!
