Half Pound: About 2 cups. Diamond nuts are made for homemade. Since 1912 when we were started by a group of California walnut farmers. Diamond of California was on a mission to bring the bounty from California's walnut farms to Central-Valley, California, America's tables. From the beginning, we sought out the very best with the knowledge that Diamond nuts would be used in treasured and new family recipes. Flavor: Farm to table.
