I don’t know if all tea parties end in five empty bottles of bubbly, but mine did. It started innocently enough with the one—for rhubarb bellinis, you understand. The next four went down smooth, and after seven hours of girl talk and dranking, so did I. But the real “wow” of the party? Not that I used half of a pair of curtains I never hung as a tablecloth, but that I spent an hour whisking egg yolk and oil into mayonnaise for the sandwiches served with tea. And it worked.
