Easy Substitutions:
You can use store-bought lemon curd.
Store-bought lemon juice may be used for this recipe, but the flavor will not be as strong and may have a metallic flavor.
Our Best Tips For Success:
When making the curd, the texture should be about pudding consistency. It takes anywhere from 10-25 minutes to thicken. Just be sure to use a GLASS bowl and place over a simmering (not boiling) pot of water.
Don’t waste the egg whites from the curd! Use them to make our meringue cookies or save the rest for breakfast!
Don’t skip lining your pan!
Fresh juice is always better. While using store-bought is convenient, the flavor of fresh squeezed lemons is unmatched.
You can use a rubber spatula to fold the liquid ingredients into the dry ingredients to ensure you don’t overwork the dough. Mix until just blended together and you don’t see any flour. The dough is very stiff and may seem a bit dry, but once all the flour is incorporated, it will be fine!
The cookie dough is a little sticky. Be sure to clean your hands often when rolling.
Even when fully baked, these cookies should be pale. You do not need to brown them!
Don’t skip coating them with powdered sugar.
For the best results, sift the powdered sugar before you roll the cookies!
