Rock Candy is made by a process of crystallization, the same process that produces quartz and diamonds in nature – with a different ingredient, of course. It is made by breaking apart the sugar (sucrose) molecular crystal lattice and then allowing it to re-form in conditions that produce larger, purer crystals. A hot, saturated solution of cane sugar and water is poured into large tanks. Careful supervision of the cooling process produces the larger crystals, which are then harvested as Rock Candy sticks, strings, or loose crystals.
These days, various flavors are added to rock candies to diversify this product in market. Cinnamon, Mint, Saffron, Cumin, Lemon, Thyme and … are among the many flavors of this product. So, if you want to make a difference in your meals, you can use flavored candies.
On the other hand, because rock candy has a better flavor than sugar, you can break the crystals in to small pieces and easily use them along with your tea. You can also use candy powder to make syrup.
