The history of this tart dates back through the ages, being a dish that has evolved over generations. It is a perfect example of rustic food that transforms simple ingredients into something truly special. Let’s get started!

Ingredients:

For the crust:
- 200 g whole wheat flour
- 100 g margarine or butter (use butter for a richer taste)
- 1/4 l sour cream
- 1/4 l water (you may need to adjust the amount)
- 1 egg
- 1 pinch of salt

For the filling:
- 500 g leeks (about 3-4 large stalks)
- 5-6 large onions
- 2 eggs
- 1 pinch of nutmeg
- 1 pinch of cayenne pepper (optional, for a bit of heat)
- Sea salt, to taste
- 2-3 tablespoons olive oil

Preparation:

Step 1: Prepare the crust
In a large bowl, combine the whole wheat flour with the margarine or butter cut into cubes. Use your fingers to rub the fat into the flour until you achieve a sandy texture. Add the salt, egg, and cold water gradually. Mix well until the dough is homogeneous. Do not knead too much to keep the crust flaky.

Step 2: Chill the dough
Wrap the dough in plastic wrap and let it rest in the refrigerator for 30 minutes. This step is essential for achieving a dough that is easy to roll out and has the perfect texture.

Step 3: Prepare the filling
Meanwhile, clean the leeks and onions. Slice the leeks into thin rounds and the onions into slices. In a large skillet, heat the olive oil and add the leeks and onions. Sauté them over medium heat, stirring frequently, until they become translucent and slightly caramelized, about 10-15 minutes. This step will enhance the flavors.

Step 4: Mix the filling ingredients
In a separate bowl, whisk the two eggs with the sour cream, remaining water, nutmeg, cayenne pepper, and salt. Add the sautéed leeks and onions to this mixture and mix well.

Step 5: Assemble the tart
Preheat the oven to 180°C. Grease a tart pan with butter to prevent sticking. Roll out the dough on a floured surface and place it in the prepared pan. Make a few holes with a fork in the dough to avoid air bubbles during baking.

Step 6: Bake
Pour the leek and onion mixture over the crust, leveling it evenly. Place the tart in the oven and bake for 30-40 minutes, until the filling is set and the crust turns golden.

Step 7: Serve
Let the tart cool slightly before slicing. It is delicious served cold, alongside a fresh salad or a glass of white wine. A wonderful drink pairing is a mint lemonade cocktail, which will add a refreshing touch to your meal.

Helpful tips:
- If you want a richer tart, you can add goat cheese or feta cheese to the filling.
- For a more intense flavor, you can sauté the leeks and onions with a splash of white wine.
- This tart keeps well in the refrigerator, making it perfect to prepare a day in advance.

Nutritional benefits:
Leeks are an excellent source of fiber, vitamins A and K, and antioxidants, while onions add extra vitamins and minerals. This tart is not only tasty but also healthy!

Frequently asked questions:
1. Can I use other vegetables instead of leeks?
Yes, you can use spinach, zucchini, or even mushrooms to vary the recipe.

2. How can I make the crust healthier?
Replace margarine with olive oil or coconut butter for a healthier option.

3. Is it possible to make a gluten-free tart?
Yes, you can use gluten-free flour, but make sure to follow the correct proportions as the dough may require adjustments.
