My guess would be to add just a bit of hydration to the dough. "A few drops" could mean anything from just that to a tablespoon of water, depending on your ingredients - a cook would know to keep adding water until the dough gets to a good consistency. Try heavy cream, or replace some of the water with a tablespoon or two of cream if your recipe calls for more than a dash. That can give your cookies a more praline-like or fudge-like taste.
