For the peach chutney
Place all the ingredients except the peaches into a pan simmer, stirring often until you have a thickened compote-like mixture.
Add the diced peach flesh and continue to stir until thickened. Stir regularly to prevent the chutney sticking or burning.
When you are happy with the consistency, spoon the chutney into sterilised jars to cool and seal.
The chutney will be at its best after a week or so and will keep for several weeks.
For the pickled peach
Bring the water, sugar and vinegar to the boil briefly and remove from the heat to cool.
Cut the peach to wedges and place into the pickling syrup for 30 minutes. Drain the slices and reserve in the fridge.
To cook the foie gras and serve
Heat a non-stick pan over a moderate heat. Season the foie gras on both sides with salt.
Place the portions in the pan and cook until nicely browned, flip onto the second side and repeat the browning process.
When cooked, the foie gras should be caramelised on each side and moist at the centre.
Drain the foie gras well and place a piece on each place with chutney and 2 slices of pickles peach.
Finish with the amaretti biscuit.
