Quarter the potatoes and boil until tender. Meanwhile, peel and mince garlic and place in a small jar. Wash and dry the parsley, cut the stems off, then mince the parsley. Place in the jar with the garlic. Add oil, vinegar, Tabasco if using, nutmeg, salt and pepper. Screw the lid on the jar and shake vigorously to dissolve the salt. Drain potatoes and, when they are just cool enough to handle, slice them thinly onto a serving platter or into a bowl. Drizzle with dressing and serve hot, warm or cold. Serves 6 and makes great leftovers. You may also add various fresh herbs thyme, marjoram or dill, for example, if you have them in your garden. Serve the potatoes with roasted chicken and asparagus.
