Pineapple syrup is pineapple juice or fruit cooked down with sugar into a pourable syrup.
It carries pineapple flavor as well as sugar, so it is used for fruit, not just to sweeten. A cooked syrup also sits safely with cream. Heat destroys the protein-breaking enzyme in raw pineapple, which would eventually curdle a creamy mix.
Bottled pineapple syrup
Swap it in at the same measure, like Monin. A pineapple gum syrup works great too and feels a little silkier.
Homemade pineapple syrup
Peel and chop a small pineapple. Steep it for 24 hours in 2:1 syrup, then strain.
Juice and syrup mix
In a pinch, mix pineapple juice and 2:1 sugar syrup half and half. Use one and a half times the measure. The juice is raw, so keep the mix out of drinks with cream.
It sweetens the drink but adds coconut flavor and clouds it. Use it only where coconut belongs.
Won't work. It is thin and tart, with less than a seventh of the sugar.
Pineapple ferments more readily than most fruit. Homemade syrup keeps about ten days in the fridge, or a month with a dash of 40% spirit added. Bubbles climbing the side are the first sign it is fermenting. A sealed bottle is good for months, though it browns faster than most fruit syrups.
