what is the sweet than honey?

Answer 1

jaggery
sugar
sugarcane

Answer 2

If this is from the puzzle:
'What is sweeter than honey, hotter than the sun, that the king wants, and the beggar has' then, the answer will be:
Nothing. Nothing is sweeter than honey.

However, coming to scientific terms, the sweetest thing in the world is 'Lugduname'. Naturally, dates, stevia, and sugar (not much sweeter than honey) taste sweeter than honey.
