Combine the flour, sugar, and a pinch of salt in a large bowl. Add the butter cubes, rubbing them into the mix with a fork until the texture's crumbly. Beat in the eggs one at a time, mixing well after each so it forms a dough.

On a floured surface, work the dough briefly with your hands to smooth it out. If it doesn't come together, sprinkle in some cold milk bit by bit. Split it into two equal portions, press each into a flat disk, cover with plastic wrap, and leave in the fridge to cool for at least half an hour.

Cook diced pineapple, sugar, and the cinnamon stick in a big pot on gentle heat. Make a slurry with water and cornstarch, then stir it into the pineapple mixture. Keep it on the heat, stirring until it thickens and gets glossy, about 10 minutes. Remove the cinnamon stick and let it cool.

Once chilled, bring the dough out and roll each disk on a floured surface until it's thin (about 1/8 inch) and roughly 12 inches across. Use one piece to line your pie dish, saving the other to go on top.

Spoon the pineapple filling evenly into the crust-lined pie dish. Lay the second layer of dough over. Cut a little slit in the center as a steam vent. Seal and trim the edges, then crimp for a finished look. Brush the top with yolk for shine.

Preheat your oven to 350°F (175°C). Bake the pie for about 50-60 minutes, watching for a golden crust and bubbling filling. Cool it for a while before serving.
