For classic New York bakery texture, the combo of cornstarch and a touch of rice flour keeps the crumb tender yet crisp; if you prefer ultra-tender cookies, omit the rice flour and add 10 g more cornstarch. Work the dough as little as possible after adding flour to avoid toughness, and chill thoroughly if it feels sticky or warm. Baking time varies by thickness and pan type, so look for just a whisper of color at the edges. These cookies keep well in an airtight tin for a week and freeze beautifully; refresh at 300°F for 5 minutes to restore crispness. Add citrus zest, a pinch of cinnamon, or dip half in melted dark chocolate for variations.
