Choose Good Pork Heart
One of the determining factors for a delicious boiled pork heart dish is to choose a good piece of heart. Avoid buying thin and fragile heart sections. Squeeze the heart and see if the yellow liquid comes out. These parts will become tough and bitter when boiled. Absolutely do not buy dark-colored pork heart or sections with blood vessels.
It is recommended to choose the head sections of the heart because they are thicker and crispier than the tail sections. Choose round and small heart sections. Gently squeeze them to see if the inside liquid is white. Good heart sections are usually sold out quickly, so you need to go to the market early or instruct the seller in advance.

Go to the market in the morning to choose good pork heart sections.
How to Clean Pork Heart
Cleaning the heart is a very important step. Since the pork heart is the digestive system of the pig, it also contains a lot of dirt. You need to wash the heart carefully to remove these impurities and eliminate the strong smell.
However, you should not squeeze the heart too much as this will make the heart tough.
It is best to choose round and pink heart sections. Go to the market early to buy good pork heart sections.
You can use a knife or scissors to trim the fat around the heart sections. Put the heart in a basin, add 2 teaspoons of vinegar, 1 teaspoon of salt, and use your hands to gently squeeze out the liquid inside. Rinse the heart with clean water. Flush water into the inside of the heart to wash away all the liquid or gently rub it and then rinse it, instead of rubbing it thoroughly and vigorously.
Continue to put the heart in a basin, squeeze a lemon, and add some crushed ginger, then soak for about 20 minutes. Gently squeeze to clean and remove any odor from the heart sections. You can boil a pot of water, put the cleaned heart sections into the boiling water for about 15 seconds, then gently squeeze to let the liquid inside out. Rinse the heart with clean water.
Another way to clean pork heart is to turn it inside out, remove some of the fat. Add flour and a little salt to the heart sections and gently squeeze them. The flour will help absorb the sticky liquid inside the heart. Rinse the heart with clean water to remove all the stickiness. Then, wash the heart with fresh lemon juice to remove any remaining dirt and eliminate the strong smell.
Proper Boiling Method
Prepare a bowl of lukewarm water with a few drops of lemon or cold water mixed with a little baking soda, bring it to a boil and let it cool.
Boil the water before putting the heart sections in. This step will determine whether the heart will be delicious or not. Putting the heart into boiling water will make it both tender and crispy.

Add some ginger to make the heart more aromatic.
Boil the water for 2-3 minutes until the heart turns pink, then scoop it out and soak it in the lukewarm water with a few drops of lemon like at the beginning. Doing this will make the heart both crispy and beautifully white, without turning black. Usually, the total cooking time from putting the heart into boiling water to scooping it out is about 7-10 minutes (depending on the quantity of ingredients).
For young hearts, just boil for a few more minutes and then turn off the heat. Scoop them out and immediately put them in a bowl of boiling water with some lemon drops and a few ice cubes to cool them down. After cooling, scoop them out and cut them into bite-sized pieces.

White and delicious heart
The most important thing to make the boiled heart white and crispy is to boil it quickly and scoop it out immediately when it’s tender. The longer the heart is cooked, the tougher it becomes.
