1/4 of a barspoon of Xanthan gum seems too be fair too much when I tried. It turned the drink into a bland wallpaper paste. I’ll try again another time with a pinch. First drink I’ve had to bin for a long time!

Very pleasant. To make it even more fun we added 5ml cream of coconut.

Used Flor de Cana 4, fresh pineapple juice, 0.5 oz of homemade grenadine to replace the rich simple. Simple and delicious. Large pineapple flavour with body behind it. Would up the rum later on or try an aged version to get that extra flavour.

How much crushed ice is recommended?

It's exactly what the review says. My only issue is that the drink has turned into a foam on top and a very liquid bottom. Any insight?
