I saucepan over medium heat cook sugar, butter. corn syrup and salt. stir til butter melts and sugar has dissolved about 10 minutes.
Remove from heat and stir in zest, flour and nuts.pour into a bowl and place in refrigerator for at least 2 hours.
Heat oven to 350F using teaspoon roll dough into small balls about the size of a medium grape. cover cookie sheet with parchment paper place cookie ball on sheet and leave about 2 to 2 and a half inched apart as they spread..bake for 9 to 10 minutes..keep an eye as they can burn and get too dark...cool on cookie sheet for 10 minutes and place on wire rack to cool..repeat with remaining dough..you can cover the dough in bowl with saran and bake remaining dough up to a week later...they are very crispy and before they get completely cooled and dry you can wrap the cookie around the handle of a wooden spoon just for a little different look when arranging on serving plate............I am asked for recipe after one taste.
