I’m an old fool with OCD (obsessive-compulsive disorder). I was making a batch of Painkiller mixer today, and I hit a wall. I am flummoxed.

For YEARS, I’ve followed the 4-1-1 recipe. No problem in the past. But today I was making a batch, and it turned out that when you buy pineapple juice and orange juice, you get the juices in fluid oz. containers. OK? So far so good.

But … when you buy a can of Coco Lopez, I noticed you get 15 ounces BY NET WEIGHT! So, when you do the 4-1-1 ratio thingy, how do you handle the Coco Lopez?

By my measurement, one 15 oz. (by weight) can of Coco Lopez is roughly equivalent to 12 fluid oz. of liquid. So—would one use one can of Coco Lopez (≈12 fl. oz.), 12 oz. of OJ, and 48 oz. of pineapple juice?? OR one can of Coco Lopez (15 oz. net weight), 15 oz. OJ, and 60 oz. pineapple juice. The world wants to know.

See I told you I had OCD.
