Preheat oven to 350°F
Finely chop ½ cup almonds by hand or by pulsing in a food processor.
Combine chopped almonds, flour, baking soda, giner and salt in a mixing bowl.
Using a hand-held or stand mixer, cream the butter with both sugars.
Beat in the egg and extract until mixture is fluffy.
Stir in the flour mixture until just combined.
Cover and chill dough for at least 30 minutes.
Measure teaspoon of the dough or weigh out 9 grams, and roll into 48 rounds.
Place on baking sheets lined with parchment paper, and press a whole almond onto each.
Bake cookies in the preheated oven for 5 minutes. Rotate the baking sheet and continue to bake until cookies are lightly browned and set; about 4-5 minutes.
Remove from oven and cool.
