1. Wash the potatoes and dry them while keeping the skin. Using a mandoline or a knife, slice them into regular slices about 3 mm thick.
2. On a baking sheet lined with parchment paper, place a parchment paper disk (which will serve as a guide) and arrange the potato slices on top, in a circular shape, overlapping them well to form a "tart base". There should be no space between each slice. Lightly salt.
3. Preheat the oven to 180 °C (350 °F). In a bowl, mix the mustards and brush them onto the potatoes using a brush.
4. Slice the tomatoes into regular rounds. Arrange them on the "tart base", also overlapping them. Drizzle olive oil on top. Lightly salt, pepper, and sprinkle with cumin.
5. Bake for 40 minutes: the tomatoes should be well cooked and the edges crispy. Serve warm as a side dish with grilled meat or fish.
Not convinced when they came out of the oven, we were pleasantly surprised by the taste. For my daughter, I replaced the mustards with pesto on one half.
