What can't you do without?

I was going through the shopping list today and I realised my shopping staples probably sound pretty weird. I mean, if I have a few things, I feel like I've got what I need and the rest is gravy. If I don't have those things, the pantry is empty, even if it's full.

Mine are:

Zwieback, tuna canned in oil, black tea, honey, milk (tea/honey/milk almost count as a single beverage unit, actually) and almonds or pecans. And whisky. If I have guests and have to share the last of any of these, I'll be hard pressed to remain a generous hostess. Unless we're down to the last of the whisky and I'm a little sauced. Then I'm pretty carefree with what I share.
