The size of our Medium Diced Macadamia Nuts is about the same as our Dry Roasted Diced Almonds; ¼” or less in diameter. Our Macadamia Nuts are sourced straight from the only place in the United States they can be farmed - HAWAII. The reason they are only grown in Hawaii is that Macadamia Nuts need that mineral-rich volcanic soil, tropical/humid temperatures, and constant rainfall. There are many reasons Almonds cannot be farmed in Hawaii, so if you are curious, feel free to ask! Hawaii farms 90% of the world’s supply of Macadamia Nuts, so we knew we had to go straight to the source for this sweet product. The Macadamia Nuts are stored in a Macadamia-only facility, the same as all our other products to avoid cross-contamination for allergen concerns.
