How to Serve Coffee Jelly

Variations
Feel free to experiment with different flavours and add-ins. For instance, you can try incorporating various extracts like vanilla or almond for a twist on the classic coffee taste.
Add chai tea for dirty chai jelly. Swap coffee for hot chocolate, tea, fruit tea, or even a tablespoon or two sugar-free caramel syrup for a caramel jelly.
Add 1-2 tablespoons of collagen peptides for an extra nutritional boost. Serve with ice cream, custard, or on top of porridge for an amazingly tasty breakfast.
FAQs
Yes, you can use instant coffee as a substitute for freshly brewed coffee in this recipe. Simply dissolve the instant coffee in hot water according to the package instructions, and then proceed with the recipe as directed. Keep in mind that the strength of the coffee flavour may vary depending on the brand and type of instant coffee you use.
Japanese coffee jelly typically needs to be set in the refrigerator for about 5 to 6 hours. The gelatin will solidify, giving the dessert its jiggly texture. It’s best to prepare the coffee jelly in advance, allowing enough time to chill and set properly before serving.
Absolutely! The sweetness level of Japanese coffee jelly can be adjusted according to your preference. If you prefer a sweeter dessert, you can add a sweetener of your choice, such as sugar, honey, or a sugar substitute like stevia, erythritol, or monk fruit. Alternatively, if you prefer a less sweet option, you can reduce or omit the sweetener altogether. Keep in mind that some sugar substitutes may react differently with gelatin, so it’s best to use a syrup-based sweetener for a smoother texture. Feel free to experiment and find the perfect sweetness level that suits your taste buds.

I was so fascinated by this recipe for coffee jelly, I had to try it. Super good and unique. I want to try it in a cake! Do you think it would work? -
I’ve never seen a recipe like this before so I had to try it. Yes, it was fun to make keto coffee jellies and the kids even helped me. These little goodies are excellent on their own – but I must confess I added some to our ‘adult’ drinks on the patio last night. -

This is such a creative idea. I like your suggestion to how the coffee jelly can be served. Your presentation looks so refreshing. Mine turned out delicious too! -
How much instant coffee in place of Nespresso pods?

In the picture where you are holding the jelly it looks like you have the jelly sitting on a very thin base of something. What is it? A wafer cracker maybe?
-
Hi Marilyn, it is actually the fat from the butter. It looks kind of weird but tastes great with the jellies
-
-
You had to mention turkish delight in the write up. Yummo. So I think I could do it with rose water. Any ideas? Love it !
-
silly question, but are you using unsalted or salted butter in yours?
-
I just use salted butter. You get a bit of a fat crust but it is nice on the jellies. Ironically not weird at all

Hi Megan, can I ask why the nutritional value has Fat 0% when it has coconut oil and butter in it? Ty
-
Due to serving portions. the nutrition calculator does not show measure of less than 1g per portion. Basically like 40g fat / 60 serves so less than 1g per serve.
