In saucepan bring wine, water and sugar to a boil. Peel and slice peaches into wedges. Remove boiling wine syrup from heat then add peach slices. Cover and allow to sit for 10 minutes. Remove peaches and reserve syrup in refrigerator for future use. Will hold about 1 week.
In a small pot reduce the balsamic to 1/3. Remove from heat.
For this dish you will need a non-stick pan. Take the foie gras out of the refrigerator. One thing I want to point out really quickly is you will need a warm knife. When you use the knife simply have a container of lukewarm water and place the knife in it and slice a 2-inch thick piece of foie gras, slice it and season with salt and white pepper. Take the non-stick pan, place it on a gas stove, on high. Take a knife and score the foie gras left to right and this will allow the fat to be released a little bit quicker and prevent it both from sticking and burning in the pan.
Once the pan is lightly smoking, remove from heat for 1/2 a minute. Add dash of grapeseed oil. Place the foie gras in the pan score side down and place back over the heat. Continue to sear the foie gras for approximately 1 to 1 1/2 minutes making sure that the Foie Gras does not burn; turn over and cook the foie gras for a further 1 to 1 1/ 2 minutes on the other side. Remove from the heat and let rest for approximately 1 1/2 minutes. Stir in butter and lemon juice. Spoon peaches and syrup onto 4 plates, place foie gras on top of peaches and drizzle plate with reduction. To finish sprinkle a small pinch of fleur de sel on foie gras.
