These cookies are extremely decadent because they contain a single egg yolk, a stick of butter, and a half of a container of cream cheese among other ingredients.
I have prepared a large number of various lemon cookies over the years
in an effort to find the perfect combination of lemon flavor and texture, while yet preserving the cookies' ability to be soft and gooey.
After you begin adding lemon juice to the cookie dough, it becomes difficult to maintain the appropriate consistency in the dough over time.
This causes the dough to become very pliable and "watered down.
" This necessitates the addition of additional flour, which disrupts
the equilibrium of the proportion of wet to dry elements in the recipe.
