You could adjust the firmishness of it with added gelatin sheets but that may take more experimentation. I read that some people will test a small amount by putting a few spoonfuls into a jar and putting it in the fridge. I believe a small amount will jellify fairly quickly. I'm not an expert on it though. This was only my first time making it. You also don't want it to firm though it could be really rubbery haha. Finding the right balance is the challenge.

Thats what you do with jam to test the firmness!

I am intrigued but I don't know if I am intrigued enough to go for it! :OD

Yeah.
Well if you do decide to give it a try, let me know how it turns out.
