I like kosher salt as the salt flakes are huge. The large surface area means that I can actually use less salt than regular table salt. And of all the Kosher salt I've tried, Morton has the biggest flakes.
My pepper of choice is Whole Tellicherry Peppercorns. They are imported from southern India by Costco and sold under the Kirkland brand. These peppercorns are big, robust, pungent and fruity.
My pepper mill of choice is a Unicorn Magnum Plus. Mine is over 10 years old and performs every bit as well as the first day I took it out of the box. You can check it out here: www.unicornmills.com
