It is still the same old watermelon. We ate, made drinks and floats with the flesh and then made pickle with the rind and now a warm sweet drink with the rind. Nothing to throw away so no cause to complain.
Watermelon rind with skin
Rock sugar according to taste
Put watermelon rind in a big pot and enough water to cover the rinds.
Bring to the boil, then reduce heat and let it simmer for at least 1 hour.
Remove and discard rind.
Add rock sugar according to your taste. Stir until the rock sugar dissolve.
