- Preheat oven to 325 degrees F. Line cookie sheets with parchment paper or foil; set aside. In a very large bowl, combine flour, sugar, oats, coconut, walnuts, and salt; set aside.
- In a large saucepan, combine butter and golden syrup; bring to boiling. In a small bowl, stir together the hot water and baking soda; immediately add to the boiling butter mixture (the addition of the soda mixture causes the mixture to rise in the saucepan). Pour the hot mixture into the flour mixture; stir with a wooden spoon until well mixed.
- Shape dough into 1-1/2-inch balls. Place balls 2 inches apart on prepared cookie sheets. Using the palm of your hand, flatten balls slightly. Bake in preheated oven about 12 minutes or until cookies are golden brown. Cool 2 minutes on cookie sheets. Transfer cookies to a wire rack; let cool. Makes about 30 cookies.
