This classic cookie combines two of my favorite sweets: buttery-tender Scottish shortbread and satiny lilting English lemon curd. The problem has always been getting a firm enough topping and avoiding a soggy shortbread base. The special technique discovered for this recipe virtually guarantees success.

The clean, refreshing flavor of lemon makes these the perfect sweets to follow a rich Christmas goose.
