If using an ice cream machine, make sure you are following the machine instructions and freezing the cooling bowl for at least 12 hours before preparing your ice cream! The bowl has to be completely frozen for the ice cream to properly churn.
Start by steeping the milk with the cardamom pods - heat up 1 cup of milk on the stove in a small pan with the cardamom pods until you see small bubbles forming along the edge. Turn off the heat, cover, and let it sit for about 45 minutes. Once that time has passed, strain out the pods.
Now it's time to make the custard. Mix heavy cream, steeped cardamom milk, sugar, and a pinch of salt in a small saucepan.
Whisk egg yolks and the whole egg and vanilla together in a separate heatproof bowl.
Heat up the milk & cream mixture until you see small bubbles forming along the edge. Make sure not to overheat! We recommend keeping this on low/medium-low heat.
Slowly stream half of the milk mixture into the eggs to temper the eggs, whisking constantly. Add the egg mixture back into the saucepan with the rest of the milk mixture, still whisking. Heat this over medium to low heat until it for a few minutes, whisking the whole time to avoid scrambling the eggs.
Once the mixture coats the back of a spoon and you can run a finger across the spoon and it leaves a trail, the custard is ready. You can also check the temperature of the custard - once it reaches 170 degrees F, it is ready!
Strain the custard into a bowl. We like to strain it just incase there are any pieces of egg that didn't get tempered!
At this stage, we like to add a dash of ground cardamom just to give it some additional cardamom flavor and so that you can see little specks in the ice cream!
Cover with plastic wrap that touches the surface of the custard to avoid a skin forming, and refrigerate until cold. It's very important that it's as cold as the fridge, so that it doesn't thaw out the ice cream bowl too quickly.
When the custard is totally cooled down (fridge temperature!), start your ice cream machine and add the mixture to the cooling bowl (follow your machine instructions!).
Our ice cream took about 25-30 minutes to churn to soft serve consistency, which is what our machine says to do.
Once the ice cream is ready, transfer to a freezer safe container and store in the freezer.
Let the ice cream harden for another couple of hours before scooping! Enjoy!
