1 and1/2 cups sweetened lime juice(find in the liquor aisle)
2/3 cup water
1 and 1/4 cup gelatin.- perhaps you live in a magic land where you can buy measurable Knox gelatin. I, alas, do not. I think that you’ll need about 50 envelopes. Just tear and dump into a measuring cup.
Combine all your liquids in a saucepan. Over lowish heat, sprinkle in maybe an eighth of your gelatin. Whisk gently. You don’t want to be overzealous and get it too foamy. Once that seems to be well combined, sprinkle in a bit more. Keep doing this until all of the gelatin is well dissolved. Line a 10′ by 15″ jelly roll pan(you need a lip) with a sheet of parchment paper. Set in a cool place. Within an hour, it will be concealed. use the parchment paper to lift the slab of alcoholic extra firm jello onto a cutting board. I find a pizza cutter the easiest way to cut into 1″ by 1″ cubes. If you are going to serve them immediately. toss them in a mixture of green or yellow sanding sugar and a pinch of pink salt. If you arent, cut them, but don’t roll them in the sugar(it’s optional anyway) sugar is hygroscopic- it draws water out of the air- you will have very sweaty(like a marathon on Mars sweaty) gummies if they sit for any length of time with their oh so pretty,sucrose glitter.
NOW- these are very alcoholic- gelatin dissolves at about 90* and alcohol boils off at closer to 150*. Forewarned is forearmed.
