Adventures with sodium alginate

[ermintrude]

I'd use tomato water you can either do this the traditional way or use gelatine filtration.

Ideally if your deseeding a load of tomatoes just keep the pulp and filter the seeds out for maximum flavor.

The advantage is that it is clear so the spheres would look better and the taste impact would be more of a surprise.

I'd add calcium cluconate, freeze and then try to spherify. If the acidity of the tomatoes causes issues then after freezing drop the frozen spheres (or cubes they both spherify ok) into 5% calcium solution quickly and then refreeze, the external calcium layer can help form the initial skin after that the chain reaction takes over.

By painting on calcium solution then layers of alginate you can do some interesting things like this

Going to bump this again. What is the best way to heat spheres? I know MC says they can be heated to 85 C, but they start to erode on me once I start warming them.
