Devonshire russet apples (currently available from Four Seasons on the High Street,) with celery and walnuts are good in this famous salad. Don't peel the apples! Wash, quarter, and core the apples and cut into small chunks, add an equal amount of chopped celery, and coarsely chopped walnuts - to taste. Season with freshly ground black pepper and a few drops of cider vinegar, then mix with mayonnaise and a crème fraiche. Place into a serving dish and sprinkle with a little smoked paprika.
