When I picked up my daughter from school, she told me she had rice krispies at school and she wanted more. I told her we can go home and make some together as her after school snack and she said, "Theirs was yummier than yours, mommy." So I said I don't have their recipe but I will try to make it really yummy. Then she said, "Oh, I know! Just smell my breath and you will know how to make it! I just ate it so it still smells just like it, so that's your recipe!"
We then picked up my other daughter from school and when she was in the car I told her how we were going to make rice krispies when we got home because her sister had some that was really yummy and she wanted me to make it just like the one she had at school. She asked, "Do you have the recipe, mommy?" And my other daughter replied back to her promptly, "She's just going to smell my breath."
I used her recipe and made the rice krispies and she said it tasted just like it.
