Place the butter on a pan over medium-low heat and let it melt and then continue to cook over medium-low heat until it starts to foam and you'll start seeing brown bits start to form and smell nutty. Stir and immediately remo. You will get roughly about 114-120 grams (about 1/2 cup) of brown butter. Let it cool down to about 80 F/27 C before using
Prepare the cookie dough:
Combine flour, baking soda, salt, ground ginger, ground cinnamon, and ground cloves in a mixing bowl
Add the browned butter, sugar, molasses, and eggs to another mixing bowl. Whisk until thick and emulsified.
Add the flour mixture, grated ginger, and diced crystallized ginger into the butter mixture and fold until combined and form a soft dough
Chill the dough: (do not skip)
Place the dough on a piece of cling wrap and wrap over it and pat it slightly into a disc and chill in the fridge for at least 1 hour or up to 24 hours
When ready to bake the cookies:
Preheat the oven to 375 F (190 C) for a conventional oven. Please lower the temperature by 20 F/ 15 C for a convection oven. Position the rack in the middle of the oven
Line 2 to 3 large baking sheet with parchment paper
The dough is easy to work with now that it is chilled. Portion the dough into about 18 grams (about 1 tablespoonful).
Roll it into a dough ball
Roll the dough ball in the pearl sugar, lightly press so the sugar stick to the dough
Place about 1 1/2 inch apart. Depending on the size of your baking pan, you may be able to fit in 18 cookies per pan
Baking:
Place the pan on the positioned rack. I recommend baking one pan at a time for the best results. Keep the other pan chilled in the fridge while waiting
Bake for 4 minutes and rotate the pan and then bake for another 4-5 minutes. The edges should be set, but the center still appears soft, a bit undone, and puffy. This will flatten and crackle as it cools down
Cooling:
Set the pan on a cooling rack and let the cookies cool down for 5 minutes and then cool on the rack completely
