First in a pan or sauce pan, take 1 cup water and 500 grams sugar
keep this sugar-water solution on a low flame
stir so that the sugar dissolves
the solution will be sticky when you touch it
when all the sugar has dissolved switch off the flame
you can also heat the sugar solution till 1/2 string or 1 string consistency
next step will be to filter the sugar solution of its impurities
line a bowl with a strainer
line the strainer with a muslin cloth
now pour the hot sugar solution carefully through the muslin lined strainer into the bowl
heres the collected sugar syrup in the bowl
let this filtered sugar solution become lukewarm or come down to a room temperature
then rinse the lemons well in water
halve them
with a lemon squeezer, extract juice from each half in a bowl or mug
from 500 grams lemons, i got 1 cup lemon juice
if there are small seeds in the lemon juice, then filter it through a tea strainer
powder seeds of 8 to 9 cardamoms and 1/2 tsp saffron/kesar in a mortar-pestle
keep aside
now add the lemon juice to the sugar syrup
the sugar syrup should be lukewarm or at room temperature when you add the lemon juice
add the powdered cardamom and saffron
stir the lemon squash very well
now pour the lemon squash in a sterilized bottle or jar
close the lid tightly and refrigerate
when preparing the lemon squash drink, add 3 to 4 tbsp of the squash in a glass and add water
stir and serve
you can also add ice cubes in the drink or make the drink with chilled water
