I prefer to grind until smooth.
You can not pre-cut anything, just throw everything into a blender or combine and chop, it all depends on the power of your unit. My old one does better with sliced food.
Try the ready-made pate to taste, if necessary, add salt, pepper or lemon juice.
In principle, you can serve the pate immediately, it is already good, but if you let it stand in the refrigerator (at least half an hour), the taste will become more balanced, and the pate itself will be more dense. I usually cook it in the evening to serve it for Breakfast in the morning.
