If you’re good at rolling Play-doh, then this is the dessert for you to make. It looks like a rose, but it’s made of apples and dough. You cut very thin slices of apple, and put them in the microwave a few seconds to soften them. Then you roll out a rectangle of puff pastry dough, and lay all the apple slices along one long side so they hang off the edge. You fold the rectangle in half over the apples, almost like pulling up a blanket over them – that holds them in place. Then you just roll up the dough from one end to make a spiral, and bake it until it becomes golden and crispy. And here’s the math: with just 2 apples you can make 6 roses. Grab a grown-up and check out Cooking with Manuela to learn to make these yourself! Just remember to use real dough, because Play-Doh won’t taste so good.
Wee ones: How many sides does a rectangle have? For a hint, can you find something rectangular in the room?
Little kids: If you eat every 3rd apple slice that you cut (starting with the 3rd) and use all the others in your rose, what happens to the 8th slice? Bonus: What number slice is the next one you eat after that?
Big kids: If you bake 2 of these for yourself and each of your 11 friends, how many apples do you need? Bonus: The roses bake for 45 minutes. If you start baking them at 2:10 pm, will they finish in time if your friends come over at 3 pm?
Wee ones: 4 sides.
Little kids: It goes in the rose. Bonus: The 9th apple slice.
Big kids: 8 apples. You’re making 24 roses (since there are 12 of you) which have 4 sets of 6 roses, and each of those 4 sets uses 2 apples. Bonus: Yes, just in time! They’ll finish at 2:55.

Her mom had Laura baking before she could walk, and her dad had her using power tools at a very unsafe age, measuring lengths, widths and angles in the process. Armed with this early love of numbers, Laura went on to get a BA in astrophysics from Princeton University, and an MBA from the Wharton School of Business; she continues to star-gaze today. Laura’s other interests include her three lively children, chocolate, extreme vehicles, and Lego Mindstorms.
