The key to making pastries - lard

Overview

To make a puff pastry, how to cook a bowl of white lard is also the key.

Wash the lard and cut into small cubes.
It is best to cut it into small pieces so that the oil will come out easily.
Put the lard into a clean pot, add a small bowl of water, and start boiling over medium heat.
Use a spatula to turn the pot several times and the water in the pot will continue to evaporate.
When the water in the pot has evaporated and the oil gradually begins to come out, add a small spoonful of salt and simmer over low heat (be sure to use low heat).
Be sure to stir frequently. When the volume of the oil residue becomes very small and becomes golden brown and floats on the oil, turn off the heat.
The cooked oil is clear and bright.
Filter out the oil residue in the pot. Let the oil settle for a while.
Pour the oil into a container, seal it and store it in the refrigerator.
Add a small bowl of water to the pot to make the lard whiter and more beautiful. Add a small spoonful of salt to prevent oil from splashing out and scalding people during the cooking process.
