Sadly I couldn’t find any agar in Asda today, but I did manage to find some gelatine. I decided to have a go at moulding some simple shapes. This is the first of a few attempts with varying consistencies. This is probably the weakest consistency that I will try, it was the recommended 1 sachet to 550ml of water and the outcome wasn’t great. The small Ice cube tray seemed to hold it’s shape much better than the larger cubes. Perhaps it needed more than 4 hours in which to set.
I then tried with a stronger consistency, with 100ml less water and some food dye… and they came out much stronger. They lasted for 3 days in this state before they started to melt down again.
