When you make this recipe, you really want to have all of your ingredients ready to go. Here’s why: The key to these cookies is a technique called ribboning. You’ll beat the eggs and sugar together until they’re lighter in color and about doubled in volume. This adds air and lightness to the cookies, but if you don’t use it right away the eggs can deflate and your cookies will be flat. So be ready to go when the eggs are. Measure out all of your ingredients and read through the recipe in its entirety first. We promise it’ll be worth it when you taste the finished results.
