Toss your pistachios into a food processor and blend them up until they turn into a smooth, creamy paste. You might need to stop and scrape down the sides a few times to get everything evenly blended. Set this gorgeous green paste aside for now.

Pour your milk and cream into a medium saucepan and warm it over medium heat until you see steam rising from the surface. Keep an eye on it - you want it hot but definitely not boiling or it'll affect the texture of your ice cream.

While your dairy is heating up, grab a bowl and whisk together the egg yolks and sugar until the mixture becomes pale yellow and gets a bit thicker. This is going to give your ice cream that rich, custard-like base.

Once your milk mixture is steaming, carefully ladle a small amount into the egg mixture while whisking like crazy. This step is super important - it slowly brings up the temperature of the eggs without scrambling them. Keep adding small amounts until about a third of the hot milk is incorporated.

Pour your tempered egg mixture back into the saucepan with the remaining milk and cream. Cook this over low heat, stirring constantly with a wooden spoon. You'll know it's ready when the mixture thickens enough to coat the back of your spoon - usually takes about 5-7 minutes. Whatever you do, don't let it boil!

Take your pan off the heat and stir in that beautiful pistachio paste you made earlier, along with the vanilla extract. Mix until everything is well combined and you've got a uniform pale green mixture.

Let your mixture cool down to room temperature first, then cover it and pop it in the fridge for at least 4 hours, but overnight is even better. This chilling time is crucial for developing flavors and getting the perfect texture.

Once completely chilled, pour your mixture into an ice cream maker and churn according to the manufacturer's instructions, usually about 20-25 minutes. You'll see it transform from a liquid to a soft-serve consistency.

Scoop your freshly churned ice cream into an airtight container and freeze for another 2-4 hours until it reaches your preferred scoopable consistency. The patience will be worth it, I promise!
