Spherification

[Richard Watters]

Hi guys,

I am I Final Year Industrial Design student at Northumbria University. For my Final Major Project I am using Spherification on cocktail ingredients. The user combines the measured ravioli (spheres) ingredients together, adds ice and spirits to create a cocktail.

As I am looking to mass produce the Sperification technique I was wondering if any of you know of a way to increase the life-span of the ravioli so that the liquid inside doesn't all change into a gel. Are there any chemicals that would stop the reaction after the initial membrane wall has been created? The only solution that I can think of at the moment is to freeze them but I have yet to test this method to see if it works.

On another topic, does anyone know of anywhere where I can buy food grade sodium citrate in fairly small amounts? 

Thanks for your time,

Richard Watters

look up reverse spherification... only problem with that is that the membrane formed is whitish and bland and you can sense the membrane in your mouth even after the bubble has burst...

Get your liquid. Freeze it in a cube. Then make solution for spherification and sphere ice cube in solution. It will defrost and stay inside. It's a bit tricky but works. The frozen liquid when it defrosts will not gel. U still are going to have a membrane but you will always have it. Even if consumed right after its made.

If you try the icecube trick with spherification and leave it in the calcium ion bath you will end up getting a flavored solid sphere as the alginate will gel completely and there will be no liquid center.

If you try reverse sphererification the alginate will form a bland membrane outside the sphere of flavored fluid because in this case the calcium ions are in the flavoured sphere and the alginate in the bath...  (try using a flavored alginate bath for an interesting effect)
