    3 oranges, juiced, strained

    1/2 cup caster sugar

    1 cinnamon stick

    1 tablespoon lemon thyme leaves

Combine 1 cup orange juice, sugar and 1/2 cup water in a small saucepan over low heat. Cook, stirring, for 2 to 3 minutes or until sugar has dissolved.

Add cinnamon stick and bring to the boil. Increase heat to medium. Cook, stirring occasionally, for 20 minutes or until syrup thickens.

Add thyme. Set aside to cool for 20 minutes.
