1. Preheat your oven to 375°F and line a baking sheet with parchment paper.
2. In a large bowl, combine the flour, sugar, and salt. Cut in the butter until the mixture resembles coarse crumbs.
3. Gradually add the cold water, mixing until a dough forms. Wrap in plastic wrap and refrigerate for at least 30 minutes.
4. In a separate bowl, blend the almond paste, powdered sugar, and vanilla extract until smooth.
5. Roll out the chilled dough on a floured surface into a rectangle about 1/4 inch thick.
6. Spread the almond mixture evenly over the dough, leaving a small border along the edges.
7. Fold the dough over the filling and seal the edges by pressing them together gently.
8. Place the kringle on the prepared baking sheet, brush with beaten egg, and sprinkle with toasted almonds.
9. Bake for 25-30 minutes or until golden brown. Let it cool slightly before slicing.

Remember, baking is as much about patience as it is about precision. Much like my abuela’s timeless recipes, the best results come from taking your time and enjoying the process.
