One of her businesses is selling cupcakes.
I went to a car boot sale on Sunday. There were 3 stalls selling cupcakes, all with their own business cards.
Last year, a colleage left our work, Telecommunications, to start his own business. He's selling cupcakes.
Cupcakes is the bandwagon del dia.
Apparently, another of her businesses is the online selling of ... cupcakes. That's like your milkman saying he's a multiple business owner, as he sells bread, eggs and yoghurts as well as milk.
She'll be kept in especially for the "interview" episode, if they still have that, when Claude will put her through the mincer (or should that be through the Kenwood Chef?)
