¾ cup pineapple juice
In a large bowl, add the white and brown sugar, and whisk in the very hot pineapple juice.
½ cup brown sugar, ⅓ cup white sugar

2 tbsp annatto seeds or powder
Strain the annatto seed-infused and sugary pineapple juice, so the seeds are removed. Discard the seeds. The color may not be red or too vibrant and that is okay.
