This cake sits in the category of things that taste more interesting than they look on paper. Olive oil keeps it beautifully moist, the thyme adds an unexpected herbal note that works with the orange rather than competing with it, and it holds for two days without losing anything. A reliable make-ahead dinner party dessert.

Rhubarb's tartness works perfectly against the sweet meringue topping — and toasting the meringue at the table or just before serving gives the whole thing a theatrical finish that requires almost no technique. Make the cake a day ahead. Meringue goes on before guests arrive. One of the most impressive-looking desserts in the collection.
