Good question! A "delicacy" is something that is fine or intricate in texture, structure, or nature. Thus, a food delicacy would be a dish that is fine or intricate in its cooking technique, flavor, or appearance. "Dairy" is used as an adjective here, to indicate a food made from milk or milk products. So, you can understand a "dairy delicacy" to be a complex, intricate food made from dairy (milk). Ex: There are many delicious delicacies in my hometown. Ex: The necklace was a delicacy of gems and gold.
