Add yolks and sugar to a medium bowl and whisk until well combined and pale in colour (set aside).
Add milk, cream, turmeric, honey and star anise to a medium saucepan and stir on a med-high heat. Once simmering, remove from heat.
Scoop out about 1 cup of the milk and slowly pour into the yolks, all the while whisking as fast as possible. Once combined, pour back into the milk while stirring constantly.
Add milk mixture back to a medium heat and continue heating until it thickens and coats the back of a spoon. Don't allow to boil.
Place in fridge for at least 3 hours, preferably overnight to enhance the flavour of the spices.
Once cooled, pour milk through a fine strainer into your ice cream machine. Churn as per manufacturers instructions then add back to freezer for another 2 hours or until hardened.
