In a heavy bottomed sauce pan heat banana milk, sugar and salt. Bring just to the start of a boil, stirring frequently, scraping the bottom of the pan.
3 3/4 cups Homemade Banana Milk, 1 1/4 cups Granulated Sugar, 1/4 teaspoon Kosher salt
In a blender, blend the eggs, yolks and cornstarch/arrowroot starch to combine. Pour into a large heat proof bowl.
4 large Egg Yolks, 4 large Eggs, 1/3 cup plus 1 Tablespoon Cornstarch or Arrowroot Starch
Slowly drizzle the heated milk mixture into the egg/starch mixture, whisking all the time.*NOTE: pouring too fast will scramble the eggs.
Pour back into the saucepan on low-medium. Whisk constantly until mixture is very thick (aproximately 5-10 minutes over medium heat).
Remove from heat. Add the melted butter and banana liqueur, whisking until smooth.
1/2 stick (4 tablespoons) Unsalted Butter, 2 ounces Banana Liqueur
Add pudding in batches to the blender. Blend until smooth.
Pour into a fine mesh strainer over a bowl set in an ice bath (see diagram) and push pudding through the strainer with a pliable spatula. Fully cool.
