COOKIE: The sign for "cookie" involves forming a "C" shape with your thumb and index finger, and then moving it across your mouth as if you were eating a cookie.
DOUGH: The sign for "dough" involves signing "D" with your dominant hand and then making a circular motion with your non-dominant hand, like you are kneading dough.
Therefore, you would sign "cookie dough" by signing the signs for "cookie" and then "dough" one after the other.
Additionally, you could:
* Sign "eat" before signing "cookie dough" to indicate the purpose of the dough.
* Use facial expressions and gestures to convey the texture and taste of cookie dough. For example, you could make a "yummy" face or lick your lips to show you're enjoying it.
Remember, ASL is a visual language, so context and visual aids are important for understanding the intended meaning.
