Pistachio Cookies Treat (Print Version)

# Ingredients:

01 - Fine salt (just a pinch).
02 - Green gel food coloring (optional, adjust to taste).
03 - Granulated sugar (110g, a bit over 1/2 cup).
04 - Heavy cream (3/4 cup or 180g).
05 - Unsalted shelled pistachios (1/2 cup, about 60g).
06 - Almond flour (105g, just over 1 1/4 cups).
07 - Egg whites, aged (4 large eggs, 110g).
08 - Powdered sugar (125g, approximately 1 cup).
09 - White chocolate, chopped small (1 1/3 cups, 240g).
10 - Pistachio flour (1/4 cup, roughly 35g).
11 - Cream of tartar (small 1/4 teaspoon).

# Instructions:

01 - Warm up the cream with the pistachios, then blend it together with the white chocolate until smooth and creamy.
02 - Process the pistachios into a fine meal, then sift all the dry ingredients together to remove lumps.
03 - Whisk the aged egg whites with cream of tartar until they’re frothy, adding sugar a bit at a time, and whip until stiff peaks form.
04 - Carefully fold the dry mixture into the whipped meringue until everything combines smoothly with the right batter texture.
05 - Pipe out small 1.5-inch circles, then let them sit for 30 minutes to develop a slight skin on top.
06 - Bake them in the oven at 315°F for 18-21 minutes, remembering to turn the tray halfway through.
07 - Wait for the shells to cool off completely, then sandwich them with the ganache and let them sit overnight for the best flavor.

# Notes:

01 - You can prepare the ganache and refrigerate it up to a week in advance.
02 - Shells stay good in the freezer for up to two months.
03 - Once filled, let them rest overnight before serving.
04 - A kitchen scale ensures the most consistent results.
