A little bit of grated lemon zest (from just one small lemon) is all that's needed to lend bright flavor and fragrance to this delightful cake. A rasp-style grater (or microplane) produces the finest shards, leaving the bitter white pith behind. This cake is just fine as is, with afternoon tea, but equally good when dusted with confectioners' sugar or drizzled with a lemony glaze for a more special dessert.
- Preheat oven to 180 degrees Celsius.
- Grease a cake pan with butter and sprinkle with sugar.
- In a bowl, mix the sugar with the butter and beat well.
