Step-by-step Guide
Real Fish Jelly Obtained
- Wash the oranges thoroughly by scrubbing the skin with a new stainless steel fiber scrubber, without using soap (ensure that it is not a scrubber with soap embedded or one that has been used for washing dishes).
- Cut off the top and bottom ends of the oranges.
- Make five cuts from top to bottom on the orange skins, without reaching the pulp; only the skin needs to be cut.
- Insert a tablespoon between the skin and the pulp to remove the five pieces of skin.
- Bring the skins to a boil in tap water (this water will NOT be used further) over low heat, covered, for 10 minutes.
- Drain the peels and ensure they are completely dry.
- Using a tablespoon, scrape off the white part from the interior of the peels. It is not necessary to be thorough, as leaving a bit of the white part will not cause any harm.
- Clean the orange segments of any white parts that may have adhered. Reserve the peels.
- Cut each segment into four or five pieces.
- Weigh the segments and peels. Note the weight on a piece of paper to calculate the amount of sugar that needs to be added.
- Calculate and weigh the necessary sugar. Divide the sugar to be added into three parts as follows:
- 50 grams to mix with the pectin (if using it).
- Approximately half of the remaining sugar.
- And approximately the other half remaining.
- Weigh the pectin and mix it with the initial 50 grams of sugar.
- Finely julienne the boiled peels. Reserve.
- Bring the julienned peels (alone) to a boil with the water from the recipe for 10 minutes.
- Add the segments to the pot and let the fruit simmer alone for an additional 10 minutes.
- Add the first half of the sugar and.
- Continue adding the remaining half of the sugar while stirring constantly. Let it cook over moderate heat for another 10 minutes, continuing to stir.
- After this time has passed, add the other half of the sugar while continuing to stir.
- Use the hand blender to achieve the desired texture.
- Let it cook for about 10 more minutes, stirring occasionally.
- From this point, monitor the temperature constantly. Allow it to boil until it reaches 102 °C at sea level or 100 °C at roughly 1,500 m altitude.
- In theory, for the jam to be perfect, we should reach a concentration of 32-34 degrees Baumé (this is achieved when the temperature reaches 104-105 °C at sea level). This process can take quite some time, and the fruit may become overcooked and the mixture overly caramelized.
Recommendations & Tricks
- Important: Place aluminum foil around the stovetops to prevent accidents from spills and thus protect the surface.
- Important Note: When preparing citrus jam, it is essential to first boil the peels alone for about 10 minutes to eliminate bitterness and soften them.
- The natural sugars in the fruit represent approximately 8.5% of the total content; however, we need to add sugar to achieve the desired sweetness.
- The acidity (pH) of oranges is usually between 3.2 and 3.3, a level that requires adjustment for safe preservation.
- For this pH, add 1.0 gram of citric acid per kilogram of clean fruit to balance the acidity and ensure good preservation.
- Remember that 1 gram of citric acid is equivalent to about 15 ml of lemon juice; you can use the juice to achieve a fresher flavor.
- The pectin level is high, which will help bind the jam naturally without the need for artificial additives.
- To achieve the desired percentage of sugar in the final jam, aim for the total sugar content to be between 53% and 57%.
- When working with 3 kg of raw oranges, make sure to peel them and remove the seeds to accurately calculate the sugar and other ingredients.
