Boil a syrup of the sugar, water and Karo; stop as or before it reaches the soft ball stage. Let cool. Beat in the dates until they "disintegrate," then the nuts. Wet a dish towel in cold water. Spoon the candy along the middle of the towel in piles. Fold towel over; roll it, pressing firmly constantly. Leave to cool and harden. Slice approximately 1 cm pieces. Might want to roll slices in coconut, chopped nuts, etc. (Mom never did, tho'.)
