To make ice powder without lime, carrageenan and gelatin (gelatine sheets) can be used instead.

Lime mainly acts as a coagulant in the process of making ice powder, so other substances can be used as coagulants.

Carrageenan: Carrageenan is a coagulant based on polysaccharides extracted from dietary fiber extracted from seaweeds such as carrageenan and carrageenan, or polysaccharides extracted from leguminous seeds. It is white or light brown granules or powder, odorless or slightly odorless, with a slimy texture. Carrageenan is mostly used to make jelly. The texture of carrageenan is soft but very elastic.

Gelatin: also known as gelatine and isinglass. It is a glue extracted from animal bones (mostly cow bones or fish bones), and its main component is protein. Translucent yellowish-brown, with a fishy smell, it needs to be soaked in water to remove the fishy smell. The gelatine tablets that have been decolorized and refined to remove the fishy smell are more transparent in color. There are flakes, powders, granules and other forms, which can be selected according to the purpose.

The process of making ice powder:

Materials and tools: ice powder seeds, lime, boiling water, brown sugar, bowl, spoon, gauze.

1. Pour an appropriate amount of lime into cold boiled water, stir evenly, and let the mixture settle into layers.

2. Put the ice powder seeds into a filter gauze bag and rinse them with clean water first.

3. Tie the gauze bag containing the ice powder seeds tightly, put it in an appropriate amount of cold boiled water, and rub it with both hands for about 6-7 minutes until the ice powder seeds become gelatinous. (Knead with moderate force, and keep the ice powder seeds submerged in the water during the process, so that the ice powder made in this way will have fewer bubbles.

4. Pour the kneaded ice powder slurry into a fine sieve and filter.

5. Take the precipitated lime, pour the upper part of the clear water into the ice powder slurry, stir evenly, stir until the ice powder slurry is semi-solidified, and then put it in the refrigerator for about 2 hours until it is completely solid. Solidify.

6. Scoop a spoonful of the prepared ice powder into a small bowl, mash the brown sugar with warm water and cool down. 7. Pour in the brown sugar water. into ice powder, stir well and serve.
