Tart Tasty Fruit Salad

Mix sour cream, sugar, and the juice of half a lime until sugar is dissolved. Taste the mixture—it should be quite tart. Add more lime juice if you need to.

Next, fold in miniature marshmallows, orange sections (if using canned, drain first), pineapple tidbits (drained), then washed seedless grapes. Fold fruit into the cream mixture. Taste and add more lime juice if necessary. Cover and chill until ready to serve.

Just before serving , fold in lightly salted toasted walnuts.
