Thanks to this season's presenting sponsor, Driscolls, only the finest berries.

Hello young chefs, and welcome back to Mystery Recipe.

I'm Molly Burnbound, Editor-in-Chief of America's Test Kitchen Kids.

And I'm Mitzi.

I've a bit, Molly's right hand gal, and behind the scenes, documentary, capture our extraordinary air.

That's a long title.

You should see my business cards. It's more like a pamphlet.

Every week, we talk about the fun and fantastical side of a different kitchen ingredient.

And at the end of the season, we use all those ingredients to make a mystery recipe together.

So far, we know it will use water, brown sugar, walnuts, oats, and crisp rice cereal.

We are getting pretty close. Can you guess what it is yet?

We have a great episode for you today.

First off, our official ingredient, guess or avally, is back to help us figure out this week's theme.

Then, champ is getting some sun in the scoop.

And finally, everyone's favorite climate change fighting butter knife is here for this sustainable solution.

Also, I will go behind the scenes and show you the real, gritty lives of your favorite folks from the show.

I don't really think our lives are gritty, Mitzi.

Have you seen how champ lives?

No.

Pretty gritty.

Anyway, to the theme song.

Looks good. I bet taste good.
