Pineapple Jam
1.
The pineapple is peeled and cut into 500 grams (weight after peeling), and can be soaked in light salt water.
2.
Use a food processor to beat the pineapple chunks. Stir half of it into puree, and half into a slightly granular form.
3.
Put the beaten pineapple and rock sugar into a non-stick pan. Bring to a boil on high heat, turn to medium heat and simmer. Until the sugar melts.
4.
Cook until the pineapple bubbling and a lot of white froth appears, gently skim off the froth. The quality of the pineapple sauce will be better
5.
Turn to low heat and continue to simmer. Add some lemon juice or white vinegar.
6.
When it comes to the final stage, the shovel must be agitated continuously. Avoid mashing the pot. Boil until the pineapple becomes transparent and viscous. The jam is ready at this time. The whole cooking process can be completed in about 30 minutes.
7.
While it is hot, divide it into pre-sterilized jars. Close the lid upside down. This effect is similar to vacuuming. So it can be divided into a vial and a vial. After cooling, put it in the refrigerator. You can leave it for two or three months if you can't finish it.
