Shell nuts carefully and rinse well with hot water. Sprinkle salt (optional) over nuts and let drain for about 30 minutes. Spread nuts in a baking pan. Put pan in preheated oven at 350 degrees F for 10-15 minutes ONLY. Reduce heat to 250 degrees F. Let nuts brown, turning them occasionally. Nuts are done when they are a golden brown in color. This should take about 35-45 minutes at the reduced heat. Remove from oven and LET COOL.
