Preheat the oven to 200°C (gas mk 6, 400°F). Place the egg, oil, milk and sugar in a mixing bowl and beat together until sugar has dissolved. Add the lemon rind and lemon juice and mix.

In another large bowl, thoroughly mix the flour, baking powder and salt.

Add the liquid mix to the dry, and roughly mix it in - it does not have to be absolutely smooth.

Fill a muffin tray with paper muffin cases, and then fill each case approximately two thirds with the muffin mixture. Bake the muffins for 25 minutes.
