Place cream and chopped rosemary in a cold metal bowl and whisk until it begins to thicken. Set aside. Cut cheese rounds about 1/4' thick. Top each with a thick layer of the rosemary cream. Cover with plastic wrap and refrigerate until needed. (Note: pierce a toothpick in the middle of the rounds to keep plastic wrap suspended above the cheese.)
Relish: Place onion, vinegar and sugar in a small pan and cook gently for 6-8 minutes to form a light syrup. Drain and chop apricots and raisins and add to the pan. Increase heat to medium and cook for 8-10 minutes until apricots become thick and jam like in consistency. Remove and keep warm.
Pistachio Oil: Place pistachios and oil in a blender and blend until smooth. Strain through cheesecloth.
Brush bread slices on both sides with olive oil. Broil until golden and remove from oven.
Place cheese rounds on a cookie sheet and place under the broiler as close as possible to the heat. Broil until tinged with golden flecks and beautifully glazed.
Place a tablespoon of relish on toast slice and top with a slice of goat cheese. Garnish with watercress or sorrel and a drizzle of pistachio oil.
