Add the sea salt and mix well.
On a low flame, stir the butter-flour frequently and cook till it gives off a nutty scent and is lightly brown.
Meanwhile, in the second pan, bring the water to boil.
Once the butter-flour mixture is cooked, gradually pour in the boiling water, mixing constantly to avoid lumps. The halva will look like thick brown soup at this point. Fret not!
Set the halva on a low flame and let it cook, stirring frequently to avoid lumps.
Allow the halva to simmer till it has reduced by half and you see evidence of the butter beginning to separate from the pudding.
Add 1/4th teaspoon cinnamon powder and stir well before taking it off the flame.
Divide between 3 to 4 bowls, garnish with brown sugar and cinnamon / date palm jaggery / chopped dates and sumac powder / maple syrup or honey.
Serve hot.
