Soak the Snow Frog Jelly for 4 hours in mineral water. Clean and put everything into a double boiler and simmer for 4 hours on low heat.
Take care to check the water on your double boiler.
Tip - If you do not have a double boiler then try with a slow cooker.
p/s I did not add sugar but you can add a bit of rock sugar (optional)
Note - This is the most basic way I recalled being boiled by the elders in my household when young. Of course since then I have eaten boiled with home made soya milk, with snow fungus, with oat milk etc. Let your imagination run...
