A note on freezing: These bake beautifully after freezing in individual balls. Just shape into balls, smash slightly, decorate with toppings (make sure they adhere by patting them), place on a sheet pan, and freeze solid. Then move them to a freezer bag. Bake right from frozen, adding an extra 90 seconds to the bake time (or as needed).
*¹ You can use milk, semisweet, or dark—whatever kind of chocolate you prefer in your cookies. Pistachio classically goes with dark chocolate, but I think it’s equally good with milk chocolate. You can also use chocolate chips instead, but if you do, use 1 1/2 cups [250 g].
*² I love Maldon and other flaky sea salts for sprinkling on cookies, but you can use whatever sea salt you prefer. Fine sea salts dissolve as the cookies bake, so they don’t yield the best texture. And coarse salts are easy to accidentally over-use. Flaky sea salts are just right. But any will work.
*³ If you don’t have raw green pistachios, you can just use more roasted salted. Read more about them here. Your cookies will not look bright green like the ones in these photos in that case, but they’ll still turn out great. You can find raw green pistachios at Indian and Iranian/Persian markets. To grind them finely, chop by hand until they’re the texture of sand. Or do what I do and use a food processor, but be careful not to process them too long or they’ll turn into pistachio butter. Just grind them until they look like sand, and stop immediately.
*⁴ If you do not have a stand mixer, you can use a hand mixer with the egg beaters attached.
*⁵ It doesn’t matter whether they actually chill through—the key here is resting time. Thirty minutes makes a difference, but longer is even better. During resting, the flour and sugars hydrate, which results in cookies with a bakery-quality texture. If you skip this step, your cookies will turn out fine, but they won’t quite live up to their potential.
*⁶ 14 minutes will yield cookies that are crisp at the edges and chewy in the center after cooling. If you like your cookies well-done (crisp throughout with a snap), let them go for another minute or two. If you do not measure your dough balls carefully or if your oven is not well-calibrated, your bake time might be different, so keep an eye on the first batch.
