1. Sieve the plain flour into a large mixing bowl together with the baking powder and salt.
2. Dry fry the sesame seeds on a medium heat for 2 minutes or until a light browning appears. Remove from the heat and leave to cool.
3. Melt the butter in a large pan over a medium heat.
4. Once melted, pour the butter into a separate mixing bowl and combine with the milk and olive oil. Begin to add this liquid to the bowl of flour, a little at a time, mixing with a fork at first then kneading by hand. You’re aiming for a soft, elastic ball of dough.
5. Wrap the dough in cling film and leave in the fridge for 1 hour.
6. Pre-heat the oven to 180oC.
7. Remove the dough from the fridge and divide it into 2 equally sized pieces. Roll each into thin sausage shapes approx. 1 cm thick.
8. Cut the sausages to approx. 10 cm in length and bend into a U shape. Plait the 2 long parts of the U into a rope like shape. Coat the plaits with beaten egg then top with the toasted sesame seeds.
9. Prepare a baking tray with greaseproof paper, then place the plaits on top and cook in the oven for 15 minutes or until golden brown.
