Also known as
Earth rock candy

Production process
Old rock candy according to the different production processes, can be divided into three kinds of, respectively
One, the traditional Local boiling process:
1, dissolved sugar (sugar and water 10:2.5) boiled, purified with egg water (1 egg to adjust the water about 5kg), and then start filtering.
2, boiled sugar: syrup purification and filtering back to the pot boiled to 105 degrees or so, the syrup drops into a bowl of cold water, can be kneaded by hand into a soft dough, you can get out of the pot.
3, raw ice: with a large mouth bottom small metal bucket or metal box bowl as a container. Container mouth cross resting on 2 bamboo (wood), in the bamboo and wood symmetrically tied on four hemp rope, vertical in the container, in order to make the hemp rope vertical, the lower end of the twine can be used to tie on the falling objects. Container ready to pour the syrup into the container. In the container around the congestion of chaff shells, covered with paper or cloth, and chaff shells congestion cover it, more in winter, less in summer, to adapt to the needs of the temperature of raw ice.

4, out of the ice: syrup in the container for 7 days (can not vibrate, that is, crystallized into rock candy, out of the ice, the first to remove the container on the cover and congestion of chaff shells, scooped near the bottom of the crystals of the ice, will be buckled upside down in the container with a wooden frame on the cylinder, drip net after the residual water, with a stick and tapped around the container and the bottom of the icing can be taken out.
Second, raise the crystal process:
1, the pure sugar dissolved into bx70-72 degrees of supersaturated thick sugar solution (about 105 degrees).
2, injected into a shallow dish, placed on a 50-70 degrees indoor rack, about 2 weeks to generate huge crystals.
3, after the separation of honey, washing sugar, drying that is, rock candy.
Three, hanging line process:
1, pure granulated sugar dissolved into bx70-72 degrees of supersaturated thick sugar solution (about 105 degrees).
2, icing sugar liquid into the barrel or barrel described in the device, in the barrel hanging on the sheep line (according to the size of the barrel arrangement of different sheep).
3, after 1 week or so, the line will grow (crystallized) a lot of icing sugar (commonly known as pillar ice), while in the edge of the barrel will also form some crystallized icing sugar.
4, after washing sugar, drying to get the finished product.
Four, other methods
1, choose 50kg of sugar, add 10kg of clean water and stir, so that the sugar is fully dissolved in water.
2, before simmering in the sandwich pot in the sandwich, add vegetable oil, and then pour the prepared sugar solution into the upper pot, simmering with fire. When the sugar solution boiled for 5 to 6 minutes, then add 0.5 kg of saturated alum solution at room temperature, stirring while adding to make it fully mixed. Measured with a thermometer, when the temperature within the sugar solution rises to 150 ℃, cease fire cooling out of the pot.
3, out of the pot, the temperature to 115 ~ 120 ℃ is the best. The sugar solution out of the pot, into the pan on the mound with a clean quilt cover, the day the temperature inside the pan is maintained at about 90 ℃, and then every day to reduce the temperature 10 ℃, down to the seventh day.
4, if the temperature is not enough, you can add fire to raise the temperature of the pit, in general, the sugar solution in the process of crystallization, afraid of cold is not afraid of heat.
Color
Depending on the production process, boiling time, decolorization process, the old rock candy will generally appear as white (white rock candy), light yellow (yellow rock candy), light gray (black rock candy) and so on.
Effects
(1) The effects of rock sugar: tonifying the middle and benefiting the qi, harmonizing the stomach and moistening the lungs, relieving cough and resolving phlegm. -Chinese Medicine Dictionary, page 953 of the last volume
Old Rock Sugar
(2) Taste: sweet, flat, non-toxic. Attributive meridian: into the lungs and spleen.
(3) Effects: Nourishes yin and promotes the production of fluids, moistens the lungs and stops coughs.
(4) Indications: dry lung and cough, dry cough without sputum, sputum with blood.
Preservation method
Old rock candy
1, rock candy because it is easier to absorb water and moisture, and therefore should be placed in a cool and ventilated place.
2, if you find that the icing sugar moisture out of water, you can use an electric fan to blow dry or placed in the sun exposure, until dry.
3, if you find that the icing sugar surface water phenomenon (i.e. more sticky), due to the family is not easy to deal with, and easy to breed bacteria, so it is best not to eat.
