Straight-edged spatulas work best. Rolls may crack if a curved spatula is used.
Look for yogurt with at least 9% fat. Any less, and your rolls may be prone to more cracking.
Try this with other frozen fruits, such as mangoes and peaches.
On A Roll
1. Position a straight-edged stainless steel spatula at a 45-degree angle on the long side of the baking sheet and push.
2. You may need to use your fingers to start the curl.
3. Quickly push the spatula across the width of the sheet to create a roll. (If it doesn’t curl easily, freeze the yogurt a bit longer.)
