In a colander, add liver and rinse under cold water; let it drain.
Transfer the liver to a cutting board lined with a paper towel. Cover with another paper towel and pat it dry as much as possible. Trim if needed and pat again; sprinkle on sea salt and set aside.
In a medium saucepan over medium heat, melt butter. Add onions and cook until softened, about 3 minutes. Add garlic and sauté for 1 minute.
Add liver, marjoram, thyme, sage and freshly ground black pepper. Cook, stirring occasionally, until the liver is cooked outside but still pink when cut open, about 8 to 10 minutes.
Transfer the liver mixture to the jar of a blender using a slotted spoon. Add alcohol, cream cheese, hot sauce and more black pepper to taste.
Blend until smooth, pushing down the mixture a few times with a spatula. Add chives and blend again.
Transfer to a medium bowl, cover and chill for 2 hours before serving.
