Nas naran is a variety of lime which has a less sharp flavour than most other varieties, making it
a more refreshing drink. The skin of the fruit has a glossy and dimpled appearance.
Sodium metabisulphate 230ppm. (0.023%) (70ppm SO²)
A few drops of green food dye if necessary
Wash whole fruits and discard any fruit which is bad.
Cut the fruits in half and squeeze out the juice by hand or with a squeezer (this can be two
grooved wooden rollers). Separate the seeds from the juice by squeezing through muslin cloth.
Mix the sugar with the water and filter the solution through a muslin cloth. (Sugar often
contains a lot of dirt and foreign bodies.) Heat the sugar syrup to 95°C then add the Nas Naran
juice, heat the mixture to 90°C, add the preservative, heat all the ingredients at 90°C for 1
minute. Then start the filling operation maintaining the temperature of the juice at 90°C.
Hot fill the juice into bottles which have been cleaned and then steamed to sterilise them, and
are still hot so they do not crack when hot juice comes in contact with them. The bottles should
be filled as quickly as possible so that the juice is not heated for longer than necessary, or re-
contaminated because it has cooled down before being sealed in the bottle. The lip of the bottle
should be clean and dry (wipe with clean tissue paper) before placing the cap on it. Lay the
bottles on their side to cool for 15 minutes. This is a most important step to avoid
contamination while the cap fits firmly down onto the glass lip as the vacuum forms.
