Combine flour, sugar, and salt in a bowl and cut in grated frozen butter until the mixture resembles coarse crumbs.
Gradually add ice-cold water, one tablespoon at a time, mixing just until the dough holds together.
Form dough into a disk, wrap in plastic wrap, and chill for 30 minutes.
Preheat oven to 375°F (190°C). Roll out chilled dough and press into a 9-inch tart pan. Prick the base with a fork.
Bake crust for 12 to 15 minutes until lightly golden. Let cool completely.
Beat cream cheese, sour cream, and sugar until smooth. Add egg yolk, salt, vanilla extract, and lemon peel; mix until creamy.
Spread filling evenly in the baked tart shell and bake at 350°F (175°C) for 12 to 15 minutes until just set.
Allow the tart to cool completely.
Wash and dry strawberries, then arrange them neatly on top of the tart.
Heat jam and water in a small saucepan until smooth, then brush this glaze gently over the strawberries for a shiny finish.
