In a pan, add the chopped pecans over a medium heat and toast for 5-7 minutes until aromatic, meanwhile continually stirring not to burn.
Place the pecans in a bowl and set aside. In the same pan, add the fine and course semolina and oil. Continually stir on a medium heat for 10 minutes.
To the same pan, add the sugar, cinnamon, orange zest and water. Stirring continually, cook for 5 minutes until it's thick.
Once the texture has solidified, stir through the toasted pecans.
To a cake tin, preferably one with a hole in the middle, add and press down the halva mixture. Leave to cool for 10 minutes before carefully tipping over on a plate and serving.
Enjoy warm or cold.
