Cut vanilla bean in half lengthwise. Scrape out the seeds.
Combine the vanilla bean, seeds, corn syrup, salt, and milk in a medium sauce pan and heat over low heat. When milk is warm turn off heat and allow to set while vanilla bean infuses the milk, about 30 minutes.
In a stand mixer fitted with the paddle attachment, combine egg yolks and sugar and mix until pale yellow and fluffy.
Heat milk until hot (about 175 degrees F). Remove vanilla bean pod.
While mixer is on low, slowly pour the hot milk into the egg yolks in a thin stream.
Mix thoroughly and pour mixture back into sauce pan.
Heat over medium low heat until it reaches 180 degrees F. Do not allow the mixture to boil.
Add heavy cream to mixture.
Allow mixture to cool. Chill in the refrigerator until it reaches 40 degrees F, about 4 hours or overnight.
Churn in ice cream machine until a soft serve consistency, about 20 minutes. Transfer to a chilled container, cover with plastic wrap and press onto the surface of the ice cream.
Freeze until firm, about 4 hours.
Ice cream can be stored in freezer up to 5 days.
