Ingredientscrust:
 1/2 cup (1 stick) cold unsalted butter, cut into cubes
 1/4 cup plus  1/3 cup sugar
1 cup all-purpose flour
 1/2 tsp coarse salt
 1/3 cup blanched whole almonds
filling:
1 large egg white, beaten until frothy
2/3 cup packed light-brown sugar
3 tbsp all-purpose flour
3 large eggs
1 1/4 cups low-fat buttermilk, well shaken
3 tbsp unsalted butter, melted
1/4 teaspoon salt
1 cup raspberries
1-2 tbsp freshly squeezed lemon juice

Methodfor crust: 
With an electric mixer on low speed, beat butter and 1/4 cup  sugar until just combined, about 15 seconds. Add flour and salt, and  beat until dough comes together, about 3 minutes. Add one tsp of water,  if needed.  Shape into a disk. Pulse remaining 1/3 cup  sugar and the almonds in a food processor until finely ground. Scatter  half of the almond mixture onto a clean work surface, and place dough on  top. Scatter the remaining almond mixture on top, and roll out dough,  re-sprinkling with almond mixture and incorporating into dough, until  dough measures an 11-inch round. 
Fit dough into a 9 1/2-inch round tart pan with removable  bottom, pressing into bottom and up sides. Trim dough flush with rim.  Refrigerate until firm, at least 30 minutes (or up to 1 day). Preheat oven to 325 degrees.  Bake tart shell, occasionally pressing  bottom to flatten using the bottom of a glass, until light brown, about  30 minutes. Let cool.
for filling: 
In a food processor, process sugar and flour until well  combined. Add eggs; process until smooth. Add buttermilk, butter, and  salt; process just until blended. Stir in lemon juice and zest.  Pour  into crust.  You may have some filling leftover that can be used for a  mini-tart..
Bake until filling is almost set but center still jiggles slightly when pan is gently shaken, 25 to 30 minutes.
Transfer tart to a rack; cool completely.  Top with as many  raspberries as your little heart desires.  Cover, and refrigerate at  least 2 hours and up to 2 days. Lemon Buttermilk Raspberry Tart
