Trim the fat and the stringy sinews of the chicken livers and pat dry. Fry the shallots with butter in a large frying pan over medium heat until soft and slightly brown.
Let the mixture cool down then pour into a food processor.
Give it a quick blitz to combine, then add the rest of the butter and cream. Blitz until smooth.
Line a terrine dish with cling film and transfer the pate in. Alternatively, you can divide the mixture into small ramekins.
Let the pâté set in the fridge overnight.
