Blood Orange and Rosemary Jelly

Uh. We were having guests last night, and as the recipe advises to prepare the jellies the day they are being served as they could become too hard otherwise, and suggests that they'll need only 1-2 hours to set, I took a risk, and failed. The jellies were nowhere near set. Even when I went to bed another four hours later, I still found them too wobbly.

We had them for dessert tonight, and they werent hard at all, on the contrary - very difficult to get them out of the moulds in one go. Also, the rosemary was too strong, and lesser so, they were a bit sour and bitter - in a good way if you had just a bit, but too much for a whole dessert.

If you want add things as decoration, anticipate that they will float instead of sink to the bottom, and that therefore you will have to turn the jellies twice - once to get them out of the mould, a second time to turn them right side up again. I used a slice of blood orange in one of them and a tiny twig of rosemary in the other one. I also used a tray with heart-shaped ice cubes from Ikea (one similar to this one), but it was very hard getting them out in one piece. Would have been such a nice idea for Valentine's Day, but then who wants to serve a broken heart?
