Brie Tarts Golden Puff (Print Version)

# Ingredients:

→ For the Flaky Puff Pastry

01 - 175 g chilled unsalted butter
02 - 225 g all-purpose (plain) flour
03 - 150 ml ice-cold water
04 - 1/4 tsp salt

→ For the Potato & Brie Tartlets

05 - 90 g brie cheese
06 - 6 small baby potatoes
07 - 2 tbsp finely grated parmesan
08 - 1 tbsp olive oil
09 - 1 large egg, beaten
10 - 1 sprig fresh rosemary
11 - Sea salt to taste

# Instructions:

01 - In a medium bowl, stir together the salt and flour. Toss the chilled butter cubes (about 1/2-1 cm pieces) in the flour, making sure not to overmix.
02 - Pour in most of the cold water and use a blunt knife to mix into a dough. If it's still crumbly, add a bit more water, but keep it firm and not sticky.
03 - Sprinkle your countertop with flour, then stretch the dough into a long rectangle. Fold the top section over the middle, then overlap the bottom section. Rotate the dough 90° and repeat this step two more times.
04 - Wrap your dough tightly in plastic wrap and put it in the fridge for half an hour.
05 - Set your oven to 200°C (400°F). Line a baking tray with parchment paper while it preheats.
06 - Use a mandoline to slice the potatoes into thin rounds (1 mm thick). Toss them into boiling salted water for 30 seconds, drain, cool in cold water, and set them aside.
07 - Take the chilled dough and roll it into a large rectangle (15 cm by 48 cm). Trim the edges to neaten, then slice into six even pieces.
08 - Score a border around each pastry rectangle about 3/4 cm from the edge. Poke a few holes in the center with a fork and arrange them on the lined baking tray.
09 - Cut the brie into thin pieces and arrange them inside the scored border on each rectangle. Layer the potato slices over the cheese in a slightly overlapping pattern. Brush olive oil over the potatoes and a beaten egg around the edges.
10 - Sprinkle some parmesan over the assembled tarts and bake for 20-25 minutes, or until they look golden and crisp. Top them with rosemary and a tiny pinch of sea salt just before serving.

# Notes:

01 - Keep your dough super cold while working with it for the best flaky layers.
