For Clustered or chunky granola: 1. Mix your batch of granola. 2. Whisk an egg white in a small cup until it is frothy and foamy. 3. Stir the egg white into the granola. Spread the granola out in an even layer on your prepared baking sheet, and bake the granola according to the instructions in your recipe. 4. Take the granola out of the oven and let it cool COMPLETELY, preferably overnight, uncovered. When it cools completely it will be clumpy. If you pour it off the baking sheet while still hot it will break up into loose granola and not get the chance to clump up. 5. When the granola is completely cool, break up into clumpy chunks, and transfer to an airtight container for storage.
