Homemade jello (aka jelly)

I committed to experimenting with making jello from scratch in another post (https://www.reddit.com/r/ketorecipes/s/0sgXjjbbdE).

It went faily well and was easy, but there was a glitch with the flavouring. It actually tasted good in the end, but I would recommend taste-testing as you go and adjusting as you like.

1 oz = 28g

12g beef gelatine powder

520ml/g water (~2 cups)

62g blackberries, mashed

42g lemon juice

"Raspberry flavor" (this seemed to have had no actual flavour)

1/8 tsp stevia powder (concentrated type)

12 drops monk fruit sweetener

I sprinkled the gelatine powder into 1 cup of boiling water, mixed it in, and let it sit for a few minutes.

Added the lemon juice and sweeteners. Added the raspberry flavor a little at a time and kept tasting, adding more, untill I used the whole bottle but it didn't seem to have anything but the slightest taste. It did, however, have a kind of slightly gummy, viscous texture which was weird.

To give some flavour, I added all the frozen blackberries I had on hand (62g).

I added the rest of the water and refrigerated overnight. It set beautifully.

The Frontier Co-op Raspberry Flavor liquid I happened to have but never used before, turned out to have no flavour at all. So I threw in a handful of blackberries, defrosted and mashed.

Commercial jello has an acidic profile. The one I saw had three different acid additives. I used lemon juice to replicate this.

I was unable to find the nutritional value of the "raspberry flavor" so that's not included in my calculations.

BTW, where I live, jello is called jelly and gelatin is called gelatine.
