Portuguese Custard Tarts

Ingredients

• 1 ¹⁄₂ cups plus 3 tbsp. flour
• 1 ¹⁄₄ cups butter, cubed
• ¹⁄₂ tsp. salt
• 1 ¹⁄₃ cups sugar
• 1 ¹⁄₄ cups milk
• 6 egg yolks
• 1 tsp. vanilla extract
• 1 pint blueberries
• Pulp from 3–4 ripe passion fruits

Instructions

1. Toss together 1 1⁄2 cups flour, butter, and salt in medium bowl. Add 6 tbsp. ice water; form into a rough ball (don’t mash butter). On a floured surface, shape dough into a 6″ × 12″ rectangle. Fold like a letter. Roll out into a 6″ × 12″ rectangle; fold again. Roll out and fold 3 more times. Cover; refrigerate for 1 hour; repeat rolling and folding process 2 more times. Cover; refrigerate for 1 hour.
2. Roll out dough into a 12″ × 18″ rectangle. Tightly roll up long side to form a cylinder. Cover; refrigerate for 1 hour. Cut crosswise into 24 slices. Working with 1 slice at a time, lightly flour, roll into a 3″ circle, and press into 2 1⁄2″-wide, 3⁄4″-deep pie tins with sloping sides. Transfer to baking sheet and cover; refrigerate.
3. Put sugar and 2⁄3 cup water into a small pot. Bring to a boil over medium-high heat without stirring; reduce heat to medium and boil for 5 minutes. Whisk together 1⁄4 cup of the milk with remaining flour in a medium bowl. Bring remaining milk to a simmer and, while whisking, pour into flour mixture. Whisk in sugar syrup and let cool until warm. Whisk in egg and vanilla to make a custard.
4. Preheat oven to 400°. Fill each tart by two-thirds with custard. Top each with 1⁄2 tsp. passion fruit pulp and 2 blueberries. Bake until pastry is light brown and custard has just set, 16–18 minutes. Let cool on a rack.
