Sift the flow into a bowl. Add the salt and sugar. Mix.
Chop the butter into cubes.
Mix the butter with the flour using your hand. Work quickly, you don't want the butter to get too soft. It's ok if you have bigger pieces of butter, the texture should be somewhat coarse. Add the cold water to the mix, a little at a time. You just need enough for the mixture to come together and hold a shape.
Press the dough into a disk about 1 inch(2½cm) thick. Wrap it in parchment paper and transfer it to the freezer for about 20-30min. Till almost frozen but still being able to shape it.
While the dough is chilling, chop the walnuts and mix with the honey. Set aside.
Pre-butter the tartlets forms with a little bit of the melted butter. The size of the forms is 3 inches(7-8cm)
Slice the apples and mix with the melted butter and cinnamon. Set aside.
When the dough has chilled. Take it out and shape it into a log.
Pre-heat the oven to 180C (350F).
Cut the log into 6 pieces about 1¼(3cm) thick.
Press each dough piece into the forms. Poke the bottom of the dough with a fork.
Fill the forms with the walnut honey mix, by pressing it down firmly.
And top them off with the sliced apples. Sprinkle sugar on top. I like to use brown sugar, but any type will work.
Arrange them into a baking tray and bake for about 30min on the middle rack. Once the edges of the tartlets are turning golden and the apples are starting to brown, they are ready.
Pull them out of the oven and let them cool for few minutes before you remove the forms.
Drizzle with extra honey on top and enjoy!
