# Add starch little by little by stirring.
# Roast the starch over low heat by the help of a beater.

# Roast for about 5-10 minutes more, the starch will turn a colour close to brown. (Total roasting time over the low heat should be 17 minutes at least.)

and water on the hot halva carefully.
# Cook over low heat for 5 minutes more by stirring. Remove the pot from the stove.
