Although there are different opinions on whether you need to add water when boiling lard, according to traditional experience and the explanation of multiple sources, adding water when boiling lard has the following benefits:
1.*Control the temperature**: The water evaporates first during the heating process, which can prevent the rapid rise in the temperature in the pot and cause the lard to overheat and burn or produce oil smoke, making the boiling process more stable.
2.*Reduce stickiness**: Adding an appropriate amount of water in the initial stage can help the fat dissolve slowly without sticking and gelatinizing in direct contact with the bottom of the pot.
3.*Improved oil yield**: Due to water evaporation and heat absorption, lard can be slowly refined at a relatively low and stable temperature, which helps the oil to precipitate more fully from the oil residue and increase the production of lard.
4.*Ensure color and quality**: By adding water to boil, you can avoid premature zooming of oil residue, so that the final lard is white in color, rich in fragrance and better in quality.
Therefore, in practice, many housewives and the older generation tend to add an appropriate amount of water when boiling lard to achieve a better boiling effect. However, it should be noted that the amount of water should not be added too much, and as the water evaporates, it should be turned to low heat and boiled slowly in time to avoid the oil temperature being too high.
