What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why be careful with raw cookie dough?

The Big Idea

We are careful with raw cookie dough because raw flour and raw eggs can carry germs! Baking heats the dough enough to kill many of them, when it is cooked all the way through. A no-bake dough is only safe with heat-treated flour and no raw egg.

Flour Is Raw

Step one: flour is raw. Flour comes from grain grown in fields, and it is not treated to kill germs. Germs such as E. coli can hide in raw flour, so tasting raw dough is risky.

Eggs Can Carry Germs

Step two: eggs can carry germs. Raw eggs may carry Salmonella. Cookie dough usually has both raw flour and raw eggs, which is a double risk.

Baking Makes It Safe

Step three: baking makes it safe. When cookies bake all the way through, heat kills many germs. That is why we wait for the cookies to cool and never eat the dough raw.

A Closer Look

Let's take a closer look at safe dough choices! Baked cookies are safe once fully baked. Edible dough uses flour that was heat-treated. It also has no raw egg. Regular raw dough, even a tiny bit, is not for tasting.

Quick Facts

Quick facts! Heat finishes the safety job in some recipes. Even licking the bowl or beaters counts as tasting raw dough. Wash your hands, bowls, and spoons after handling dough. Ovens are hot, so a grown-up does the baking.

Think Like a Scientist

Now, think like a scientist! With a grown-up, find a no-bake dough recipe. Check that it uses heat-treated flour and no raw egg. Never taste raw dough. And never taste raw dough!

Outro

Baking makes cookie dough safe, so wait for the finished cookie. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
