Almost everything in the Store-Cupboard Ingredients list is usually on hand here. The exceptions are self-rising flour (have never used, despite a childhood of Grand Ole Opry ads <g>), Crisco (which is what I take the 'vegetable fat' ingredient to be), and dark brown sugar. We use light brown sugar with morning coffee, and I sub it for dk brown unless there's some very specific need -- which I haven't run into, not being much of a baker or dessert maker. Usually sub the light brown for tablespoon quantities of white sugar, too, just because it's right to hand on the prep counter.
Most years, the granulated white sugar and confectioner's sugar tins go for loooong periods without being opened -- summer jams and simple syrups for drinks for the white sugar, Christmas bourbon balls for the confectioner's. If I were to bake just a tiny bit more (i.e., any), it would be the kind of cakes that are decoratively dusted with confectioner's sugar; I love that look.
Lemons or limes are almost always on hand, and their absence indicates a period of less-cooking-going-on-than-ideal. Actually, same is true for wine; in a period when I'm cooking regularly, there's a bottle of red or white around. I feel lucky that there's a winery in our county, so that drinkable wine is inexpensive enough to cook with -- and has a super-low carbon footprint.
