I kow that there are a bunch of other 'ibles on this subject, but they use the powder based Jelly, and I used the already jelly-ish Jelly.
Step 1: Materials And Tools!
One 135g package of strawberry Jelly. The ones I found in a cupboard in my kitchen had a best before date of february 2007, but they seemed to be usable anyway.
A bottle of Vodka
Step 2: Lets get cooking...
Place the Jelly cubes in the measuring jug.
Add boiling water up to 285 ml (1/2 pt). Since my jug is marked with even hundreds of mililiters i had to guess what was aproximately 285 ml.
Stir until the cubes are completly dissolved.
Do _not_ make up to 570 ml (1pt) with cold water.
Instead, make up to 400 ml and then add cold vodka until you are at the 570 mark.
Again, I had to make an aproximate guess.
Step 3: This is the pouring part...
Put everything in the fridge and wait for a couple of hours for it to set.
Step 4: The only step with no pictures -_-
They did not keep their form after leaving the container, and they tasted rather strongly of the alcohol, but they were definetely edible.
