That should be fine. It sets basically the same as jello would. Unless they’re like licking it or something
And actually agitating it during the setting may be beneficial. I’ve never played around with this but the whole idea behind this is a gel structure that is broken. That’s why ideally you have an automatic stirrer during the ice bath portion to continually agitate the mixture as it cools. But I’ve made this 4 times now and had the gels come out to varying degrees of hardness after refrigeration because of varying levels of calcium. Sometimes it comes out fairly liquid, sometimes it comes out basically like gelatin, but every time it has been successful.
Fair point. The reason I used the phrase “invented the technique” is not to imply that he invented fluid gels (that was Norton and Campbell) but to imply he invented this recipe, which refined the idea of fluid gels (relatively shortly after their discovery in the early to mid 90s) to manage viscosity to the point that 2 opposing gels could be held in a cup vertically.
That said semantics are important so good point
