The easiest way to cut liver is when it is still half frozen (when removed from the freezer) because the texture is like jelly. Cut your liver into cubes, discarding the transparent liver skin.
Slice onion and chop garlic fine.
Heat up a frying pan with olive oil. Saute onion slices and chopped garlic until soft.
Stir in the liver pieces and sautee with the pan covered over a slow heat setting until the liver is cooked through. That usually takes 5 minutes if cut small.
Transfer to a food processor and add the remaining ingredients, salt, pepper, crushed allspice berries, oregano, ground paprika or cayenne pepper, worcestershire sauce. Blend the whole content to a smooth paste.
Serve directly as a spread over bread or crackers with some pickle garnish or bell pepper, or store it in an airtight container to use anotehr later.
Notes
Serve on a crispy bruschetta or whole wheat bread and garnish with capsicum, little green pickles, olives or garden cress.
