Pre-heat oven to 400 °F (200°C), Put a baking sheet in the oven to heat.
In a small pot add the milk and heat it on low medium heat until it's warm. Mix in the vanilla and lemon juice, remove from heat and let cool.
In a large bowl whisk together the flour, salt and baking powder. Add butter and mix it in with the other ingredients until it looks like fine crumbs. Do it with a fork or with your hands. Then add the sugar and mix.
Then add coconut flakes and combine, add the cooled liquid and combine it quickly, work the mixture with your hands until it becomes a soft dough and then pat it into a circle approximately one inch thick.
Cut the dough into slices,(approximately 8 slices) and brush the tops with a little milk. Place the scones on the hot baking sheet (being very careful) you previously put in the oven.
Bake for about 10 minutes until risen and golden on the top. Let cool before serving.
