I mopped up as best I could - cake top, floor, cupboard doors, table legs. Then I called J, my friend and partner in aging catastrophes, to come for a cup of tea and some "vinegar chocolate cake."
"Oh!" she enthused. "I've made chocolate cake with vinegar before. It's quite good."
"No doubt you did it on purpose though, right?" I queried.
There was a pause. "But..." she began and I could hear a quiver of laughter in her voice.
"But," I reiterated and told her about the bottle and the crash and the river of aromatic liquid.
By this time she was laughing helplessly. "This reminds me of the angel cake you made, the one with too much water. The crust was quite good, though." She hiccuped.
Like its predecessor, the chiffon cake had some quite edible parts, those slices where the vinegar hadn't penetrated. And with enough whipped cream, even those bits that smelled like salad tasted almost like chocolate.
