Combining delicate flour and delicious butter can make all kinds of cookies, but making cookies doesn't just require flour and butter; other ingredients such as eggs, powdered sugar, etc., are also needed, and a certain ratio must be mastered. Only with the right recipe and ratio can you make delicious cookies!
Basically, the ingredients needed to make cookies are butter, powdered sugar, eggs, and cake flour. Additionally, the recipe will be adjusted according to personal taste preferences, and different recipes will, of course, produce cookies with slightly different flavors.
Generally speaking, when making cookies, the amount of butter accounts for 70% of the amount of flour. Only this amount can make the cookies more fragrant, crispy, and delicious.
Once the amount of butter is determined, we then need to look at the amount of powdered sugar. Many people choose to use white sugar instead of powdered sugar, but using white sugar will actually be sweeter! As for the amount of powdered sugar, it is generally 50% of the amount of flour. Some use 70% or 30%, which is also fine; it just depends on personal preference for sweetness.
Next, come the eggs. Generally, for every 100 grams of butter, 50 grams of egg is used. It can also be 30 grams of egg yolk and 50 grams of egg white; this is flexible. The important thing to note is that eggs must be added in parts, and you must avoid an oil-water separation, otherwise, the result will be far from the ideal cookie.
