1. Firstly, determine the total volume of liquid to gel. 2. 20 g PURAGEL is sufficient to form a solid gel with 1 liter of liquid (in winter time 15-17 g is sufficient). At temperatures above 30 °C, 30 g PURAGEL might be needed 3. Then for every 1 g of PURAGEL, dissolve the powder in 10 mL of cold liguid and allowing it to swell for 10 minutes (i.e. 20 g in 1/4 liter of cold water). 4. After it is fully swollen, transfer the PURAGEL into the rest of the liquid that was brought to a boil before. However, do not let the container stand on the heating plate, since PURAGEL should not boil. This would result in the loss of gel strength! 5. It is also sufficient to bring a quantity of liquid calculated in step 3 to a boil, while the PURAGEL swells with a certain amount of liquid. Transfer the swollen PURAGEL into this hot liquid and stir well, then add the thus obtained solution again to the remaining amount of liquid. This results in a faster gelation! Please note always: Pour PURAGEL mixture into the molds after it is cooled down. Addition of vinegar or extracts will add a darker colour to PURAGEL. |
