There are certain cat foods humans can eat. I would be very careful about going too far with the blowtorch, Blondie. When cat food is burned, all sorts of chemical compounds are formed. And, Mr. Bowie likes the dessert served in a traditional manner.
Crème brûlée, also known as burnt cream, crema catalana, or Trinity cream is a dessert consisting of a rich custard base topped with a contrasting layer of hard caramel. It is normally served at room temperature.
Crème brûlée is usually served in individual ramekins. Discs of caramel may be prepared separately and put on top just before serving, or the caramel may be formed directly on top of the custard, immediately before serving. To do this, sugar is sprinkled onto the custard, then caramelized under a salamander broiler or with a blowtorch. (From Wikipedia, the free encyclopedia)
