The biggest problem is usually the juice. Tomatoes release a lot of it when the cook, and it threatens to swamp the flaky crust, making the whole thing soggy and drippy instead of crisp and concentrated with tomato flavor.
There are varying remedies for this — setting the tomato slices on paper towels for a while, roasting them before layering them into the crust, etc. — and every recipe is different. We've rounded up quite a few, below, some of which involve making a crust from scratch, while others use puff pastry. One, from Melissa Clark, makes individual tartlets (so pretty).
You can add olives or other toppings, but we like ours simple — maybe some basil and a bit of cheese. What about you?
