A pate' of sorts? Recipe if you have one? Look great!
I use the proportions you see in the first picture. A little more liver than egg, by volume.
Add the egg and liver to a pot of boiling water and boil for 8 minutes.
Peel the egg, roughly chop the liver, and chill them in the fridge until cool.
Dice the shallot and add to a mini prep with the egg and liver, enough mayo to make it spreadable, and s&p.
Time is not friendly to this stuff so make it right before you plan to eat it. It's pretty simple, but this is how my mother made it. My sister made a fancy pate one year. It was fantastic, but it scored zero Thanksgiving tradition points.
