I have the same question as j.holbrook.7c6b12...what's the right cocktail glass here? The proportions seem off as you can fill up two standard coupes with these ingredients, but then you're only getting one 1 ounce of rum in each coupe. Liquor.com: is this for 2 servings, or is there a glitch with the amounts?
Great tip for the extra straight coconut cream, I substituted that for the heavy cream and delighted in what I found to be the perfect balance of coconut taste. I also used some pure cane sugar syrup I had handy instead of the demerara simple syrup and garnished with a piece of fresh cane sugar... cheers!
After drinking these for another couple weeks, I've achieved the coconut flavor I was looking for by substituting the demerara (sugar) with an equal measure of the best coconut cream I could find. With that one little change, I can't imagine a better tasting piña colada.
