To make the coconut syrup, take 4.5 cans of coconut milk, 1/2 quart of coconut chips, toasted and 15 oz of water. Bring the coconut milk and water to a simmer, turn off the heat, and add the coconut chips. Cover and let steep an hour. Strain and weigh the liquid. Add twice as much demerara sugar by weight to the liquid and stir to combine. As a note, the linked recipe omits what to do with the chips.
