Ever since we went to Maui on our honeymoon, I knew your Dad had a great love for anything with macadamia nuts.  He loved eating them alone (either salted or sugared), in recipes (such as over fish), and most of all in my homemade milk chocolate macadamia nut cookies that I began making for him.  In fact, when it came to making homemade cookies, this was the cookie of choice.  And, not any chocolate chip would do.  It had to be milk chocolate, which blended just perfectly with the buttery nuts.  Ironically, none of my children are not that fond of nuts, and prefer that I omit them from brownies, muffins, and cookies.  I say give them a try.  You have no idea what you are missing!
