can you use Crisco shortening stick with butter if cookie recipe call for butter?

It's not recommended to substitute Crisco shortening stick for butter in a cookie recipe that specifically calls for butter. Here's why:

* Flavor: Butter adds a rich, buttery flavor that Crisco shortening lacks. The cookies will taste different, possibly blander.

* Texture: Butter contributes to the texture of cookies, making them chewy and tender. Shortening will produce a more dense and crumbly texture.

* Spread: Butter helps cookies spread during baking, leading to a more even shape. Shortening will result in cookies that spread less.

However, you can partially replace the butter with shortening. This can help achieve a combination of flavors and textures. A common ratio is 75% butter and 25% shortening.

Here's what to consider:

* The recipe: Some recipes may work better than others with this substitution.

* Your preferences: If you like a softer, chewier cookie, use less shortening. If you prefer a crispier, more crumbly cookie, use more shortening.

It's best to experiment with small changes to find what you like best! You can always make a small batch of cookies using a partial substitution to test before making a full batch.
