The story of â€˜Gustavâ€™s Saladâ€™. Gustav was a local from one of the Southern Dutch isles who had developed his own strain of â€˜melt-in-the-mouthâ€™ butterhead lettuce. He used to ride his bicycle all over the village, a bucket filled with lettuce heads dangling from his handlebar, delivering them to numerous tables in the village. He let some of his lettuce mature to grow seed for the next year so that he could grow more of his own flavourful lettuce. Gustav continued growing lettuce known by the locals as â€˜Sla van Paâ€™ (Pappyâ€™s Salad) for more than 40 years!
