In a medium bowl, combine the Greek yogurt with 1/2 tablespoon of lemon curd. Taste and add more lemon curd if you'd like it sweeter or more citrusy.
In a small glass or mason jar, spoon in a layer of blueberry compote (or fresh or thawed frozen blueberries).
Spoon in half of the lemon yogurt mixture, followed by half of the granola.
Add another layer of blueberry compote (leaving some for the topping), and add the remaining yogurt mixture.
Top with the rest of the granola and the blueberry compote.
The layers starting from the bottom are: blueberry compote, yogurt, granola, blueberry compote, yogurt, granola, blueberry compote.
Sprinkle with lemon zest if using, and enjoy immediately!
