Eureka! I finally figured it out! I'm working on a "tub of beer" cake, so naturally I needed to make some ice cubes out of isomalt. But batch after batch kept turning out in various shades of yellow--SO frustrating!! Then I finally stumbled onto the right way to do it-my last 3 batches in a row were PERFECT! So I thought I'd share what I learned with everyone.
Start with 2 cups of isomalt in a saucepan over medium-high heat. When the bottom layer of isomalt starts to melt, turn the heat down to medium and stir occasionally--keep a VERY close eye on it. When the temperature hits 280, start to stir constantly--gently, but constantly--and watch the temperature carefully. The moment that the temperature hits 340--quickly remove from the heat and immediately pour it into the mold. I didn't even have any bubbles at all whereas my earlier batches where I stirred less had LOTS of bubbles. (FYI-The 2 cups of isomalt made 24 ice cubes--I was using Wilton's silicone brownie-bite pan)
Hope this helps someone!
