Place a medium shallow pan and ice cream maker in your freezer.
Whisk the heavy whipping cream, half and half, and almond liqueur in a medium saucepan over medium heat until it's hot but not boiling.
In a small bowl, combine the egg yolks, sugar and salt. While stirring constantly, slowly pour ½ cup of the hot mixture into the yolks. Then transfer the warm yolk mixture to the pot while continuing to stir. Whisk the mixture over medium heat until it's almost simmering.
Pour the ice cream mixture into a heatproof bowl through a fine mesh sieve. Let it cool, then cover and place in the refrigerator overnight.
Day 2
Following your ice cream maker's instructions, churn the cold mixture until it's thick and creamy like soft ice cream. A few minutes before it's done churning, add the halved cherries.
Pour the ice cream into the frozen shallow pan. Cover and freeze.
