After much experimentation with reverse spherification this weekend, I completely failed to get an acceptable product. Caviar didn't form properly. In particular, when dropped from an eye dropper, the drops would not penetrate the bath and so did not form proper spheres. The height I dropped from made no difference on the effect. I also had issues with my spheres glomming together in to a single mass if they touched.
I used a 0.5% sodium alginate bath with room temperature Dasani bottled water (which makes no mention of any sort of calcium on the label). I did a 2.5% Calcium Lactate Gluconate in to Peach Looza. I also tried a 0.5% Calcium Chloride solution with the Peach Looza. I tried thickening the peach juice with 0.5% Xanthan gum, but that didn't seem to make a difference.
The gelling process was working, and was fine if I placed the peach in the bath slowly, but I found it impossible to make small caviar with an eye dropper as the peach just sat at the surface. Once they did eventually sink, if there were multiple spheres, they would form a single mass as soon as they touched.
Any suggestions to fix these issues? I wanted to make a large amount and then hold for service, but I was unable to make any at all, really.
