Seedless, mini watermelons
This summer our local grocery has been selling Dulcinea seedless mini watermelons, which are about the size of a cantaloupe. I love watermelon, but previously I almost never purchased one because they were HUGE and just too much for two people. These mini watermelons are perfect though - easy to carry and store in the fridge. I've been making quite a bit of Watermelon-Limeade with them, but also just enjoying them sliced.
Mini watermelons seems like one of those ideas that somebody might have thought of sooner, but I don't remember seeing them before.
We have also been enjoying Dulcinea's Extra Sweet Tuscan Style Cantaloupe - great with some smoky ham or prosciutto.
