Rock sugar, also known as crystal sugar, is a type of sugar that comes in large crystals or rocks. It is commonly used to sweeten drinks and desserts, add texture, or as a garnish. However, rock sugar can be difficult to find in some areas or expensive to purchase. Fortunately, there are a few suitable substitutes for rock sugar that can be used instead in recipes.
What is Rock Sugar?
Rock sugar, or sugar candies as they are sometimes called, are large, solid crystals of sucrose or table sugar. The crystals are typically between 5-10 mm in diameter on average. Raw sugar is dissolved, purified, and then crystallized through a process of heating and cooling to produce the large rock candy crystals. This allows the sugar to take on a pliable, hardened crystal form.
Other common names for rock sugar include crystal sugar, sugar cubes, and sugar rocks. The large crystal structure helps the sweetener dissolve slowly, enabling long-lasting sweetness. The sugar rocks can range in color from clear to golden or even other tinted hues depending on any impurities. Their texture is hard and crystalline.
Rock sugar has been produced for centuries, first in India and China. It was originally used for medicinal purposes as well as to sweeten foods and drinks. Today, it is commonly found in East Asian cuisine and desserts as well as some beverages like iced tea. The sugar rocks add visual interest and texture in addition to a sweet flavor.
Reasons to Substitute Rock Sugar
While rock sugar provides some benefits, there are also reasons you may need or want to use a substitute:
– Rock sugar can be difficult to find or expensive to purchase in some areas. Since it is a specialty product, it may not be available at all grocery stores.
– Recipes sometimes require just a small amount of rock sugar as a garnish or for visual interest. Using a substitute can avoid having to buy a whole package of rock sugar.
– Crystalline rock sugar can be difficult to break down and dissolve properly in some foods and drinks. Substitutes can provide more reliable sweetness.
– Rock sugar has a high price point per pound compared to more common white granulated or brown sugars. Substitutes can provide cost savings.
– Some people simply prefer the flavor or texture provided by sugar substitutes compared to rock sugar. Personal preference can make alternatives more desirable.
– Dietary restrictions like diabetes or a low-sugar diet may require avoiding pure rock sugar. Substitutes can allow people to still enjoy the sweetness.

Substitution Options
There are a number of alternatives that can provide the sweetness, texture, and visual appeal of rock sugar. Here are some of the best options:
White Granulated Sugar
Regular white granulated sugar makes an easy 1:1 substitute for rock sugar. The grain size is smaller but the sweetness and solubility are similar. Granulated sugar provides a more uniform texture and sweeter flavor compared to larger rock sugar crystals. The fine grains dissolve easily.
Use the same measurement of granulated sugar in place of rock sugar. Combine it with liquids when cooking, sprinkle it on cereals or fruits, or use it as a garnish if some texture is desired. The crystals won’t be as large and pronounced but can provide sweetness more reliably.
Brown Sugar
Brown sugar can also substitute for rock sugar with some slight flavor and appearance differences. The brown color and molasses notes provide deeper flavor complexity compared to plain white rock sugar. However, the fine grain may dissolve more quickly than large rocks would.
Use an equal amount of packed brown sugar in place of rock sugar called for in recipes. Be sure to pack it firmly to match the volume. The moisture content may slightly alter the texture but sweetness levels are very similar.
Sugar Cubes
Plain white sugar cubes are essentially miniaturized versions of rock sugar. The compacted crystal structure dissolves slowly like rock candy and provides visual interest. However, sugar cubes are smaller than typical rock sugar with a more uniform shape.
Simply substitute one medium-sized sugar cube for every 1-2 teaspoons of rock sugar. The cubes can be used to sweeten drinks or added on top of desserts. Place them in a food processor or smash with a spoon to create larger crystals if necessary.
Coarse Raw Sugar
Unrefined coarse raw sugar is another excellent stand-in for rock sugar. The light golden color and large crystal size mimic the physical properties well. The molasses flavor also provides more complex sweetness like brown sugar.
Use a 1:1 ratio to replace rock sugar with coarse raw sugar. The crystal size may vary slightly but will dissolve slowly and provide texture. Coarse raw sugar works especially well in drinks, sauces, and on top of baked goods.
Turbinado Sugar
Turbinado sugar is a blond-colored, coarsely crystallized sugar that makes a great rock sugar substitute. It has a light molasses flavor profile and large crystals that provide crunch. The golden color also gives an appealing visual element.
Substitute turbinado sugar 1:1 for rock sugar. It dissolves well and provides sweetness with a hint of richness from the molasses notes. The crystals are slightly smaller but give a similar effect sprinkled on desserts or used in candy recipes.
Sanding Sugar
Sanding sugar has large crystals like rock sugar but is opaque white instead of clear. The crystals have defined edges. It does not clump together, so it keeps a loose, sandy texture. The visual appeal and texture make it an ideal substitute.
Replace rock sugar directly with an equal amount of sanding sugar. It works well for decorating cookies, cupcakes, and scones to add sweet crunch. The grains won’t dissolve as fully so the texture remainspronounced.
Crystal Sugar
Crystal sugar is sometimes used interchangeably with rock sugar, but it can also refer to large sugar crystals made in a different process. Crystal sugar has an elegant, sparkly appearance and dissolves slowly like rock candy.
Simply substitute 1:1 for rock sugar. It provides the same large crystals and texture but may be easier to find than specialty rock sugar. Crystal sugar works anywhere you want sweetness combined with crunch like in drinks or sprinkled on top of treats.
Dextrose Powder
Pure dextrose powder can also be used to replace rock sugar. Dextrose is essentially glucose made from corn. It provides pure sweetness without altering flavor or color. The powder dissolves easily but doesn’t mimic the crystal texture.
Substitute dextrose using a 3:4 ratio – for every 1 cup of rock sugar use 3/4 cup of dextrose powder. Be sure to break up any clumps in the powdered sugar when measuring to get an accurate quantity. The texture will be smoother but sweetness level remains similar.
Honey
Honey is a sweetener that brings its own distinct flavor profile. It can be used to replace rock sugar, though the results may have a different taste. Honey provides a thick, syrupy consistency and floral, earthy notes.
When substituting honey for rock sugar, use about 3/4 cup for every 1 cup of rock sugar. The thickness and moisture content alter the volume. Also reduce any liquid in the recipe slightly to account for the extra moisture in honey.
Agave Nectar
Like honey, agave nectar is another liquid sweetener that brings its own unique qualities. It has a thinner, more pourable consistency compared to honey. The flavor is subtler with sweet, neutral notes.
Replace rock sugar with about 2/3 cup agave nectar for every 1 cup of rock sugar called for. Agave nectar is sweeter than sugar so less is needed. Adjust other liquids in the recipe accordingly since it adds moisture just like honey.

Tips for Substituting
Here are some helpful tips when substituting other sweeteners in place of rock sugar:
– For large crystals, look for raw sugar, turbinado sugar, sanding sugar, or crystal sugar. Granulated sugars won’t have the same pronounced crunchy texture.
– Brown sugar, turbinado sugar, raw sugar, or honey can provide deeper molasses flavor notes compared to plain rock sugar.
– Opt for granulated white sugar, dextrose, agave, or simple syrup for pure sweetness without altering flavor.
– Reduce liquids slightly in recipes when using moist sweeteners like brown sugar or honey.
– Sugar cubes are easiest for approximating rock sugar’s shape and appearance, though the size is smaller.
– Grind sugar cubes, raw sugar, or granulated sugar in a food processor to create larger crystals as needed.
– Store any leftover substitute sugars in airtight containers to prevent hardening or moisture loss.
