1. Prepare the Lemon Yogurt Base: In a medium bowl, combine the plain Greek yogurt, fresh lemon juice, honey (or maple syrup), and lemon zest. Stir everything together thoroughly until the mixture is smooth and well combined. Taste and adjust the sweetness or lemon intensity to your preference. The yogurt should be creamy and have a pleasant balance of sweet and tart.

2. Gather Your Glasses: Select two clear glasses, jars, or bowls. Using clear containers allows you to see the beautiful layers, which is part of the appeal of a gourmet parfait.

3. Start with a Yogurt Layer: Spoon about one-quarter of the lemon yogurt mixture into the bottom of each glass. Spread it gently to form an even layer. This creates a solid foundation for your parfait.

4. Add a Berry Layer: Sprinkle half of the fresh mixed berries over the yogurt in each glass. Aim for an even distribution of colors and sizes.

5. Introduce Granola Crunch: Add half of the granola over the berries in each glass. This layer provides a wonderful textural contrast to the creamy yogurt and soft berries.

6. Repeat the Layers: Add another layer of the lemon yogurt mixture (another quarter) over the granola in each glass.

7. Finish with Berries and Granola: Top the final yogurt layer with the remaining fresh berries and a sprinkle of the remaining granola. You can arrange the berries artfully on top for a more visually appealing finish.

8. Serve Immediately: These parfaits are best enjoyed fresh to ensure the granola remains crunchy. If making ahead, see the storage tips below.
