Combine the flour, sugar, and salt in a bowl and mix. Add in the diced, chilled butter. I used a pastry cutter to cut through the butter in order to thoroughly mix with the other dry ingredients. The end mixture should be quite flaky.
Start adding in the chilled water a bit at a time. I typically don't measure it out, I just pour a little at a time and begin kneading with my hands. Continue to add water in increments until the dough completely holds together. Don't go overboard though, you don't want something that is sticky!
Roll into a ball and then flatten. Cover with plastic wrap and chill in fridge for at least 30 minutes. If you are able to chill the dough for longer, you'll get a flakier crust since you're letting the fats from the butter solidify (which is my favorite!).
Preheat the oven to 400° F/170° C.
Prepare the filling
Peel, core, and slice the pears into thin pieces.
In a mixing bowl, toss the pears with the spices and add in the lemon juice.
Put it all together
Separate the dough into 6 equal pieces. You can be more precise and weigh it out in grams or you can eye-ball it as I tend to do.
On a floured surface, roll out the dough until around 6-7 inches or 15-20 cm in diameter. You want to make sure to leave enough space to place in your pear filling while being able to fold the edges in. I left around 2 inches/5 cm around the edges.
Place the pear filling in the center. You can really decorate it however you want. I put them in two columns and stacked them up against each other. Once you fold the edges over the pear filling, you can fill in empty spaces with more pears. I wanted these to be completely stuffed! Crimp the edges for something more aesthetically pleasing.
Brush the melted butter over the pears and crust. Sprinkle with granulated sugar. Because I was making this for an Asian audience (who have a more milder sweet tooth), I didn't want it to be overwhelmingly sweet, so I used around 1 teaspoon on the pears and 1 teaspoon on the crust.
Bake in oven for 30 minutes or until crust has turned a beautiful golden color.
