This post on DIY sugar cubes looked so simple- and it is. Who knew making sugar cubes was even possible? But when I started looking for small enough molds, there wasn't anything out there that really excited me. Because I had my heart set on diamonds. Enter silicone putty molds.
To make sugar cubes, all you need is sugar, water, and some molds. The ratio of sugar to water that worked best for me was 6 teaspoons of sugar, and 1 teaspoon of water.
Just pour the sugar into a bowl, and make a little well in the center for the water.
Add the water, and with a fork, scrunch up all the sugar until it's evenly saturated. It feels and looks like wet sand at this point.
Fill up the molds, really packing it in. Let them sit at room temp- and this is where things started to get hairy. My guess, is that the surface area of the molds is so small, that it takes an extra long time for these to dry out. Like 2 days to dry out. It also took a toothpick to pop them out of the molds, and when they all had been removed, only 8 of the 12 were standing. And of those 8, only 6 looked passable. I'm not ready to give up on them yet, though. someday, I will have diamonds.
