Gelatin foam - set base

Ken_259952

Hey guys,

I once encountered a completely set base in my siphon after refrigerating the siphon for a few hours. I used about 2% gelatin, aiming for a rather stable foam. Just to make sure: This is not supposed to happen, as in, it's just supposed to make the mix more viscous, not turn into a gel, correct? It's just that with our store-bought european gelatin, about 1.5% are probably enough to create stable gels, so I assume this is not what we're after..?

Thanks!
Ken

Seems like you guys are as lost for words as I am. Just today I had another thought on this: I'm not a big fan of gelatine, so I made a rather thin (0.5%) gellan f fluid as a base for a foam. Worked beautifully. So, if I remember correctly, doesn't gelatine have the ability to heal itself within 24h even if you shear the gel? Since this is not a desired behavior, this must mean that I've been overdosing my gelatine bases for foams... but still, at 2,25% percent 170 bloom, which, converted to the 250 bloom we have here in Europe should be around 0,81x2,25 = 1,82%, I get a hella thick gel. Any other thoughts?
