If you have an ice cream maker that requires the bowl to be frozen, make sure to put it into the freezer 24 hours before you want to make ice cream.

Figure out what container you want to cure the ice cream in and place that in the freezer to get very cold.

In a small heat-proof bowl or measuring cup, beat the egg yolks and set near the stove.

Have a fine mesh strainer over a medium bowl ready and a larger bowl that the medium bowl fits into with ice and water ready for an ice bath.

In a medium saucepan, combine the cream, milk, glucose, and the sugar. The syrup doesn’t have to be completely blended in. It will smooth out as the mixture heats.

Carefully split the vanilla bean, but don’t scrape the tiny seeds out just yet.

Add the vanilla bean to the milk mixture.

Bring the mixture to a boil, constantly stirring to not scorch the bottom.

Remove the saucepan from the heat.

Slowly add about ½ cup of the hot mixture to the egg yolks, beating as you go to temper the egg yolks. (This prevents them from overcooking.)

Quickly beat the tempered egg yolks into the remaining hot milk mixture, constantly stirring. Using a small whisk here will make it combine quickly.

Place the saucepan over medium-low heat and cook, constantly stirring, until the custard has reached 180° and coats the back of a spoon. This will happen very quickly, so don’t walk away.

Strain the mixture through a fine mesh strainer into the medium bowl to remove any bits of cooked egg.

Place the bowl into the bigger bowl with the ice and water to stop the cooking process.

Take the vanilla bean that was also strained out and carefully scrape the tiny seeds using the side of a knife.

Place the scraped bean along with the tiny seeds into the strained custard. Or this is where to add the paste if you are not using a bean.

Occasionally whisk or stir the mixture as it cools to break up the seeds.

When the mixture is at room temperature, place a piece of plastic wrap directly on the surface of the custard to prevent a skin from forming.

Let the custard chill in the fridge for at least 3-4 hours to cure or preferably overnight (the longer it chills, the more time the vanilla bean has to seep in the custard.

When you are ready to make the Ice cream

Remove the vanilla bean from the custard.

Make the ice cream according to your machine’s directions.

When the machine is done, transfer the ice cream to a storage container and let it firm up in the freezer for 3-4 hours. Or you can serve soft serve ice cream directly from the machine’s bowl.
