Siphon (gelatine + tea) problem

johG_241326

Hi all.

I tried making tea foam (a lot of earl grey + water + a bit of sugar + gelatine). It worked nicely, but after like 30 seconds, it seems like the foam "broke".

I used app. 300 ml liquid, three sheets of gelatine - mixed it very good, and three chargers, and shaked the siphon a bit between each charge.

Did you allow the gelatin to bloom? If you did, What did you bloom the gelatin in? What is the bloom number of the gelatin used? What was the mass of the gelatin used? Did You heat the gelatin or keep it cold when You incorporated it. Define "mixed it very good" how did you mix it?

Did you allow time for it to cool? If using for a warm foam, gelatin can break down easily. Also consider adding .1% xanthan. I did similar things with an almond milk whipped cream recently and it worked well.

The gelatine bloomed in cold water until it softended. I squeezed it to get rid of the water and added it to the tea mix. I whisked it in the almost boiling tea mix for a couple of minutes with a flat whisk. I'm not 100% sure of the gelatine sheet weight, but I think it's 2 grams per sheet - so app. 3% gelatine ratio. I let the mixture cool down to body temperature (or even a bit colder). I will try addng a bit of xanthan.

Edit: Would the number of chargers used (three) have anything to do with the fact that the foam didn't keep it's "foamyness" that long?
