# How to Mix Your Favorite Ice Cream

April 30, 2017

Every ice cream flavor is different. Some have crunchy bits, some have streaks of gooey fudge or caramel, and some just melt in your mouth. But as this chart shows, lots of ice creams use the same “base” ingredients as each other. On the left, the chart lists the base foods like chocolate, nuts, and marshmallow. Then colored lines point from each one to all the Ben and Jerry’s ice cream flavors that use that food. First we see all the chocolaty ice creams like S’mores and Phish Food, then the cookie and cake types like Cinnamon Buns, and so on, making beautiful stripes. Coffee and marshmallow don’t show up in many ice creams, but even they have their fans. Follow the colored lines to find out what’s in your favorite ice cream!

Wee ones: If Coconut Seven Layer Bar really uses just chocolate, cookies, nuts, and caramel, how many base ingredients is that?

Little kids: How many different colors for base ingredients can you count in the chart? Bonus: If Vanilla Caramel Fudge uses 3 of them — vanilla, chocolate, and caramel — how many does it skip?

Big kids: 36 of the ice creams use chocolate, while 21 use cookies or brownies. How many more use chocolate than cookie/brownie? Bonus: If 1/3 of the chocolate ice creams *also* use cookies, how many of the 21 cookie ice creams don’t use chocolate?

The sky’s the limit: If 36 ice creams use chocolate, 16 use caramel and 20 use nuts, and of those there are 2 ice creams that use all 3 ingredients while 10 other ice creams use 2 ingredients, how many ice creams use any of the three base ingredients?
