Stable foam?

[fishy]

How do I create stable foam? (the type you whisk and skim off the top not the isi kind)

I recently tried just pure cream and a touch of liquid hickory smoke but it turned in to cream sooner than i wanted it to.

I have agar and gelatin in mind but how do i use it? just desolve it in and go?

thank you

Lecithin works. I have a pot of Soy Lecithin from a healthfood shop. Comes as granules. Just dissolve in the liquid. Don't need much. Half a tea spoon in a half a milk pan of whatever I want to froth seems to do the trick.

You're missing a surfactant to stabilize the air-water interface. This why lecithin is used. Adding anything that stabilizes emulsions would probably do the trick: pure lecithin, egg yolks, mustard powder, etc.
