Will my jelly set?

[LookAtThatArtwork]

I've just made some jelly with the sachet. I've accidentally used a pint of boiling water rather than half and half of hot and cold. Anyone know if this is going to set the same or should I discard and make a new one?

It will just take slightly longer to set.

If you don't want your jelly to set, put some pineapple or papaya juice in (contain enzymes that break down gelatine).
