I've never used that recipe before. It seems like this recipe is designed for quantity over quality. By using 1.5 cup juice, you're forcing yourself to use way more unflavored gelatine than necessary. Too much gelatine can cause tough/chewy spots in the gummies. I'm also unsure about using coconut oil in gummies, as it tends to separate, leaving you with uneven doses & little chunks of coconut oil in the gummies.
I would recommend using avacado oil or EVOO as the carrier oil.
The recipe I use calls for:
1/4c infused oil
1/4c light corn syrup
1/2c water or juice
6oz Jello mix (either 1 large box or 2 small)
2) .25oz packs gelatine
There are many different ways to skin that cat.... this is just how I do it. I'd be interested in how they turn out if you do them that way. I'm always looking for better ways.
