My grandma never made these muffins, but she could have, relates John T. Ham, Jr., of Cedar Rapids, Iowa. "They're good, old-fashioned grandma quality. Serve them any time of the year, but take along some for a breakfast picnic. Or wait till a picnic draws close and bring them out as an end-of-the-day treat." At least four generations of John's clan have rated Devil's Backbone State Park near Strawberry Point, Iowa, their top picnic spot.
