Hey June, so glad you loved the Jello Slice.. Its very popular around here too. Thanks for the review.
I’m in Australia, where did you buy the sugar free jello? the diabetic jelly crystals are sweetened with very unhealthy artificial sweeteners
Thank you
Hi Wanda,
I’m in Australia also. There is a product called “Simply Delish Sugar-free Jelly Mix” which is sweetened with erythritol which is a natural sweetener. I hope that helps.
I have made this several times and it is delicious!
Hello Lianne, thank you for your kind words, glad you like them.
Hi,
As a vegetarian I can’t do gelatin – is there an alternative?
Thanks, (in Aus)
Hi Rj,
You could try using a vegetarian alternative like agar agar in the equivalent amounts. I haven’t used agar agar in a very, very long time so I cannot be sure how it would turn out. Please let me know how it turns out if you do decide to try it 🙂
Hi you mentioned anything about lining the pan with baking parchment so I put it straight in. Im worried its not gonna come out now ;(
Hi Maria,
I don’t line the pan for this recipe, all you need is a nice thin spatula and the bars will come out easily.
Thanks Gerri,
So looking forward to making it 🙂
Hi,
I want to make this recipe so I need to make the unsweetened condense milk, does your recipe for the unsweetened condense milk be enough to make the Jello Slice, if not how much do I need to make it.
Cheers,
From Australia.
Hi Karen,
Yes it does! The sweetened condensed milk recipe makes approximately 500ml and you only need 340ml for the Jelly slice 🙂
Hello! What do you mean by pouring the jello mixture over a spoon? I don’t understand how to perform this step in the recipe. Thank you in advance for your response.
Hi Penelope,
You want to avoid pouring the jello directly onto the layer below as it can create holes and cracks, and if the jello is too warm it can start to dissolve the layer.
What you want to do is to hold a spoon a 1-2 inches above the slice (in a flat position, as if it is full of liquid and you are raising it to your mouth), then pour the jello onto the spoon so it trickles off on all sides. It’s a much gentler approach that pouring the jello straight on top.
I hope I’ve explained it well enough for you 🙂
Gerri
