The traditional British round lettuce. Soft leaves, packed with flavour, perfect in a sandwich. I remember eating lettuce sandwiches when I was really young - just a few of these leaves, sprinkled with salt between two slices of buttered bread.
Loved those little watercress tea sandwiches on buttered white bread.
