How to make this traditional pineapple agua fresca with an electric juicer
1 ripe pineapple, skin removed and chopped in spears (don't remove the core; that can go through the juicer as well)
3 cups cold water or more to dilute concentrated juice
Remove top and bottom of pineapple and cut the skin off all the way around the fruit. Chop into spears, keeping the pineapple core intact.
Put all the pineapple, including the core, through your electric juicer. It should yield about 3 cups of concentrated juice. It's normal for the juice to have a foamy top straight out of the juicer.
Strain the concentrated juice through a fine mesh sieve into a pitcher to remove the foamy top, then add 3 cups cold water and stir well to incorporate. Taste to see if you want to dilute more; if so, add water in increments of 1/4 or 1/2 cup at a time until the juice is to your liking. You should not need to add any sugar or simple syrup.
Serve over ice. Store in the refrigerator for up to 4 days.
