1
In a large bowl, mix flour, sugar, and a teaspoon of salt.
- Wheat flour: 300 g

- Salt: to taste
2
Put the butter cubes in a bowl. Rub the butter with the flour by hand, but don't overdo it: the mixture should be uneven, and the butter should not melt.
- Butter: 230 g
3
Evenly sprinkle the dough with crushed thyme.
- Fresh thyme: 4 tablespoons
4
Make a well in the center of the bowl and gradually add 1 tablespoon of ice water into it. Start kneading the dough, but not too vigorously. After about 30-40 seconds, the dough should become sticky. Pour in 1 tablespoon of apple cider vinegar and continue kneading the dough until smooth for 1-3 minutes.
- Water: 5 tablespoon
- Apple cider vinegar: 1 tablespoon
5
If the dough remains dry, gradually add 0.5 teaspoon of cold water while kneading.
- Water: 5 tablespoon
6
Once the dough texture is smooth and uniform, wrap it in plastic wrap and refrigerate for at least 1 hour.
7
Preheat the oven to 190 degrees.
8
Pour water into a large pot and add diced potatoes (2.5 cm). Bring to a boil over high heat and cook for 10 minutes until the potatoes soften but are not fully cooked. Then drain the water and set the potatoes aside.
- Purple Potato: 250 g
9
Roll out the dough for the quiche to fit a medium pie dish, place the dough in it, and cover with parchment paper.
10
Pour dried beans onto paper for pre-baking, place the mold in the oven and bake the dough base for 10-12 minutes until partially cooked, then set aside.
11
While the base is baking, whisk eggs, milk, and cream in a small bowl. Season with salt and pepper to taste. Add potatoes, sliced leeks, and 3/4 cup of Gruyère cheese.
- Chicken egg: 6 pieces
- Milk: 120 ml
- Cream: 120 ml
- Leek: 0.5 piece
- Grated Gruyere cheese: 1 glass
- Salt: to taste
- Ground black pepper: to taste
12
Once the base is baked, carefully remove the parchment paper with the beans and save it for reuse.

Fill the test base with egg-potato filling. Sprinkle with remaining Gruyère cheese and bake for 40-45 minutes until the crust and filling are golden brown.
- Grated Gruyere cheese: 1 glass
