These lettuces might be tiny, but they put the mini head lettuce on the map all on their teeny-tiny little rounded, green backs. Famous for a reason, they consistently produce dense, green, heads at a young age that are absolutely delightful to work with. Cutting them in half reveals all kinds of tiny little openings that are ready to fill with delicious ingredients. They really are a marvel of plant breeding. In France, these tight mini heads are known as "sucrine" and are highly prized.
