Add a little water (enough to facilitate blending) to the almonds and blend to a fine paste.Strain through a fine sieve or muslin cloth and add some more water to the left-over almonds and blend and strain again.Make the liquid up-to 2 cups, by adding water if necessary.

Add sugar to the strained almond liquid and dissolve over low heat.When it dissolves, increase the heat and bring to a boil and let the syrup cook.Keep skimming off the scum as it cooks.Cook till a drop of syrup pressed between two fingers, forms a thread (one-thread consistency).

Add the cardamom extract and the kewda essence. Strain through a muslin cloth and cool.When cool, mix the potassium in a little of the syrup first and then add to the whole lot.Store in clean airtight bottles.
