Cut guavas into small pieces and cook it in a vessel
with some water. When it is done, smash and strain out the pulp in a sieve.
Remove the seeds and boil the guava pulp. Stir
it continuously with a wooden ladle. When it boils add the sugar slowly
into it. Boil it well by stirring continuously.
To test whether the jam is done, pour some jam on a dry
plate. Allow it to cool and tilt the plate. If the jam is ready, it will
fall in flakes and not in drops.
When the jam is done, add the citric acid to it (if needed
add the essence) and remove from fire and pour it to a dry bottle. When
the jam cools, close the mouth of the bottle.
