Clip a candy thermometer to the side of a medium pan.
In a medium saucepan, heat the milk, cream, honey, over medium-high heat for 5-10 minutes until it starts to simmer. If you’re using a candy thermometer, the mixture should reach 110 F. Remove the pan from heat, and add in the lavender. Cover and steep for 30 minutes. I added the lavender to a tea ball to keep them contained to one place, but you can just stir in the leaves if you don't have a tea ball. Remove the tea ball, or strain out the lavender.
Return the pan to heat, and bring the temperature up to 110 F again, and remove the pan from heat to cool slightly.
Meanwhile, place the egg yolks in a small bowl. Slowly whisk in about 1/2 c of the milk mixture to temper the egg yolks until the yolk mixture is smooth and uniform.
Pour the yolk mixture into the pan with the milk, whisking until combined.
Return the pan to medium heat and, stirring continuously, cook the mixture for about 10 minutes, until the mixture thickens slightly.The temperature should reach 165 F. Remove the pan from heat. Stir in the vanilla and salt.
Pour the ice cream mixture through a strainer and into a large heat-safe bowl. Allow to cool slightly before covering and transferring to the fridge.
Chill the mixture for at least 6 hours, or overnight.
When ready to make ice cream, pour the mixture into an ice cream maker and churn according to manufacturer instructions. Mine turned into smooth, fluffy ice cream in about 20 minutes!
Enjoy immediately if you prefer a soft-serve consistency, or transfer the ice cream to freezer-safe containers and freeze for a scoopable ice cream.
