To prepare guava jelly, the first step is to extract the strained fruit juice from ripe guavas. This can be done by cutting the guavas into small pieces and then using a juicer or blender to extract the juice. The amount of guava juice needed for the recipe will depend on the desired quantity of jelly.
Once the guava juice is extracted, the next step is to calculate the amounts of other ingredients required for the jelly. This includes water, pectin, acid, and sugar. The water is added to dilute the juice and achieve the desired consistency. Pectin is a natural thickening agent that helps the jelly set, and the amount used will depend on the specific brand and instructions provided.
Acid is added to enhance the flavor and help with the jelly's shelf life. Common acids used in jelly-making include lemon juice or citric acid. The amount of acid added will depend on personal preference and the level of tartness desired in the jelly.
The sugar is added to sweeten the jelly. The amount of sugar needed will depend on the sweetness of the guava juice and personal preference. It is important to note that sugar also acts as a preservative and helps with the jelly's texture and shelf life.
To begin the actual jelly-making process, the guava pulp, pectin, water, and a small amount of calculated sugar are mixed together. This mixture is then heated for 3-5 minutes under agitation. The heat helps activate the pectin and dissolve the sugar.
During this heating process, it is important to stir the mixture continuously to prevent it from sticking to the bottom of the pot and burning. It is also important to keep an eye on the temperature and ensure it does not exceed the recommended range for jelly-making.
After the mixture has been heated and the sugar and pectin are fully dissolved, the remaining sugar is added gradually while stirring continuously. This allows the sugar to dissolve evenly and prevents clumping.
Once all the sugar is added and dissolved, the mixture is allowed to boil for a few minutes to ensure proper setting of the jelly. A small amount of the mixture can be tested on a chilled plate to check for desired consistency. If the mixture sets and forms a jelly-like consistency, it is ready to be transferred to sterilized jars for storage.
Before pouring the hot jelly mixture into the jars, it is important to ensure the jars are clean and sterilized. This can be done by boiling the jars in hot water for a few minutes or using a sterilizing solution. The hot jelly is then carefully poured into the jars, leaving a small headspace at the top.
Once the jars are filled, they should be sealed tightly and allowed to cool at room temperature. As the jelly cools, it will set further and achieve its final texture. It is recommended to store the jars in a cool, dark place to extend their shelf life.
Preparing guava jelly involves extracting the strained fruit juice, calculating the amounts of other ingredients, mixing and heating the ingredients, and then transferring the hot mixture into sterilized jars. It is a process that requires attention to detail, proper measurements, and careful handling to achieve a delicious and well-set guava jelly.
