# What is the compound I made from KNO3 and table sugar which subsequently exploded when I exposed it to a flame?

I mixed 75% $\ce{KNO3}$ and 25% $\ce{C12H22O11}$ (by volume) in boiling water to make slow burn fuses. Some of the product became a thick brown paste.

After drying, a hard cake of an approximate 1 tablespoon amount exploded when lit. What compound did I make?
