Air bubbles in sugar ice cubes

post #1 of 9
Thread Starter 
I am trying to make sugar ice cubes and I keep getting air bubbles.
I am using a silicone brownie mold for the cubes.
I boiled 1/2 cup sugar and 1/2 cup light corn syrup to 250 degrees.
Then I poured it immediately into the molds.
What did I do wrong?

You poured it immediately into the molds. icon_smile.gif

Once your sugar is up to temp (preferably 338F), remove from heat and place the pot in a 275F degree oven for about 15 minutes until all the bubbles disappear. Then, pour into your molds.

Also, try pouring your sugar high and thin... Not sure if that makes sense but hold the pot or whatever you're pouring from as high above the brownie pan as possible pouring a thin stream of sugar...

That is so good to know! Because I had the exact same question that KarolynAndrea had! Thanks!

I just did poured sugar shot glasses and mini liqueur bottles. It definitely helps to put the hot sugar in the oven (275F) for at least 15 min. and then pour high and thin to fill it 1/4 up, waited a min., then poured the rest. I got fewer bubbles doing it that way compared to when I poured it immediately into my molds.

I would suggest putting your oven at 300, just to keep it a little warmer. You'll gain longer working time by doing this (25 degrees makes a big difference with sugar). You do need to let it rest for a bit before pouring.

One other thing you may notice is that after you're done, there may be small bubbles on the surface. Silicon releases gas when the hot sugar gets it, which causes this. If it happens, take a small torch and they should go away.

Sounds like I need to get a torch!
