½ cup (100g / 3.5 oz) fine semolina flour + 2-3 tablespoons extra to dust the pan
1 cup (200 g) sugar
3 medium eggs
2 teaspoons vanilla
½ cup (65g) cornstarch
2 tablespoons (30g) butter + extra to butter the pan
Topping
1 medium egg
2 tablespoons sugar
2 tablespoons water
1 teaspoon ground cinnamon
To Serve (Optional)
powdered sugar
ground cinnamon
Instructions
Preheat the oven to 392°F / 200°C.
Make sure you have the right pan size before beginning. Please see note below.
Generously butter a pan and sprinkle some semolina flour all around. Tap the pan to remove any excess flour. Set aside.
Make the custard filling
Place the milk, semolina flour, the sugar, 3 eggs, cornstarch, and vanilla in a medium or large saucepan. Place over medium-high heat and whisk continuously until it thickens, about 7-10 minutes.
Remove the saucepan from the heat and whisk in the butter. Whisk until the butter melts.
Pour the custard filling into the prepared pan and even out the top with a spatula.
Make the topping
Add the egg, cinnamon, sugar, and water to a small bowl and whisk everything together until well-combined.
Brush the egg mixture all over the pie. Pour the remaining mixture over the pie and even out the surface with the brush.
Bake the pie for about 40-50 minutes, until golden brown. It will puff up and deflate a bit as it bakes. If you notice the surface becoming darker, cover with some aluminum foil. To test if it's done, insert a knife near the middle. If it comes out clean, it's ready.
Allow it to cool completely before serving. Dust with some powdered sugar and cinnamon, if desired.
Cover and store any leftovers in the refrigerator for up to about 5 days.
