Here is the recipe given to me by a bartender friend of mine.Unless you plan on making a lot of drinks,I would cut the ingredients down,as this makes about a litre of foam.I honestly am not sure how long it would last in the fridge,although i keep mine for a fortnight and then make a new batch.

Here goes:

550ml of water
250ml of syrup
3 sheets of gelatine

Microwave this for 2 minutes covered,then add

15grams of egg white powder

Whip this with a hand held blender,or a whisk to combine the ingredients,place it into your siphon,then charge with one bulb.Refrigerate for 12 hours then charge with another bulb.Give it a good shake each time you use it.

I only use one bulb myself as i cut this recipe down to 1/4 and use a small sized siphon.I haven't yet experimented with alcohols,although it can be done.You will have better success with liquers with a high sugar content.Alcohols and citrus juices break down the proteins in the egg white and the foam will collapse quite quickly.With this method it will last about the time it takes to finish a drink,(depending on how slow you drink).

Although i haven't tried it,you could try possibly 200ml of orgeat and 50ml of curacao to make a sort of Mai Tai Foam,but you must remember that foams generally are on the sweet side and therefore will affect the sweetness of the drink overall.

I once had a foam flavoured with Caraway seeds that was magnificent.From memory,the seeds were infused into the sugar syrup.

Hope this helps.Let me know how you go.
