1 can sweetened condensed milk
¼ t. salt
1½ c. light corn syrup
2 t. (or less) anise (licorice) oil
1 c. butter
1 t. (or less) black food color
2 c. sugar
Lightly spray or butter a 9” square (or 7″x 11”) baking pan – glass is best. (Update: can line with sprayed foil, then lift out after they’ve set up.) In a heavy 4-quart saucepan, combine condensed milk, corn syrup, butter, sugar and salt. Place over medium heat and stir with a wooden spoon until well mixed.
Cook, stirring constantly to 235º or 236º. Remove from heat and stir in flavoring, food coloring and blend well. Without scraping, pour into prepared pan. Allow to stand at room temperature for several hours. Cut and wrap. Be prepared for black teeth when you eat them!
