Have you ever been madly cooking, on top of your game - and then BAM! - a "flat tire" - no pepper in the grinder, just ran out of the right kind of vinegar, need tomato puree and all you have is diced, etc.? What's your most frustrating "flat tire"? No pepper in the grinder or forgetting to buy a spice I need is mine, I think. Either that or dumping in too much of something (herb/spice) by accident. -L.
