The bitterness of the black sesame seeds are nicely balance by the sweetened condensed milk. I make my own vanilla extract using some type of alcohol (ie rye whisky, vodka etc) so the addition of the home made extract combines the flavour of the vanilla beans with the alcohol. Black Sesame seed no churn ice cream - 3/4 cups whipping cream, 1/2 cup sweetened condensed milk, 1 1/2-2 tbsp toasted ground black sesame seeds, 1 tbsp vanilla extract (home made in neutral alcohol), pinch of salt
