Demerara Sugar — Cups to Grams

What Makes Demerara Different: Crystal Size and Molasses Content

Demerara occupies a specific position in the sugar spectrum defined by two physical characteristics: crystal size (1-2mm diameter, making them large enough to see and hear crunch individually) and molasses content (approximately 5% by weight, retained through partial refining rather than added back as in commercial brown sugar).

The production process: raw sugarcane juice is evaporated and then crystallized. The initial crystallization produces raw crystals surrounded by molasses. These crystals are then centrifuged — spun at high speed — to remove most of the surface molasses. The degree of centrifugation determines the molasses content of the final product. Demerara is centrifuged sufficiently to produce clean, distinct, free-flowing crystals (not sticky like muscovado) but not enough to remove all molasses (unlike white granulated sugar, which goes through further refining and often charcoal filtering).

The resulting 5% molasses retention is enough to give the crystals their amber color (from carotenoid and phenolic compounds in molasses) and a flavor profile that is perceptibly richer and more complex than white sugar, but not so much that it competes with the primary flavors of food it accompanies. This makes it an ideal coffee sweetener and a topping for baked goods where a subtle complementary note is desired rather than an overt molasses character.

British origins: The name Demerara comes from the Demerara River in Guyana, then a British colony. From the 17th through 19th centuries, Demerara region was one of Britain's most productive sugar-producing territories. The large-crystal, partially refined sugar produced there was exported to Britain in massive quantities and became so associated with quality and flavor that the regional name became the product name — even after the specific geographic origin became irrelevant to modern production.

Demerara vs Turbinado vs Muscovado: The Complete Comparison

These three minimally refined sugars are frequently confused with each other and with commercial brown sugar. Understanding their actual differences prevents recipe failures and misuse.

Turbinado vs Demerara — can they substitute? Yes, freely and at equal weight. Both are large-crystal, partially refined raw cane sugars with similar molasses content and identical functional properties. Turbinado tends toward slightly smaller crystals and marginally lighter color, but the practical difference in any recipe is negligible. In the UK, demerara is more commonly available; in the US, turbinado (particularly "Sugar in the Raw" brand) is more prevalent.

Why muscovado cannot substitute for demerara: Muscovado's fine, sticky, high-moisture texture is fundamentally different from demerara's large, dry crystals. Using muscovado where demerara is called for on a muffin top would produce a wet, sticky surface that spreads and absorbs rather than the intended crunchy, caramelized crust. The flavor profiles are also significantly different — muscovado is distinctly molasses-rich, almost treacle-like, while demerara is mild and toffee-adjacent.

Baking Applications: Where Demerara Excels

Demerara is a specialist sugar — not versatile in the way granulated sugar is, but uniquely excellent in specific applications where its crystal size and molasses character are assets rather than liabilities.

Cookie and scone topping: The most universal application. Roll dough in demerara before baking (for snickerdoodle-style cookies), or sprinkle 1 teaspoon (4.5g) per scone directly onto the cream-brushed surface before baking. At 375-400°F (190-205°C), the crystals partially melt and caramelize while retaining enough structure for a distinct crunch. The caramelization temperature of 320°F (160°C) is achieved quickly on the exposed surface, creating a golden, glossy, crinkled top within the first 5-7 minutes of baking.

Crumble and streusel toppings: Combine 3 tablespoons (40g) demerara + 3 tablespoons (42g) cold butter, cubed + 1/4 cup (30g) all-purpose flour + 1/4 cup (25g) rolled oats. Rub together until crumbly. Spread over fruit crisps, muffin tops, or coffee cake. The demerara keeps the crumble crispy for longer than granulated sugar would because the large crystals caramelize without fully dissolving into the fat, maintaining individual crystal texture through baking.

Banana bread with demerara crust: After pouring batter into the loaf pan, sprinkle 2 tablespoons (27g) demerara over the entire surface. During the 55-65 minute bake at 350°F (175°C), the demerara melts and reforms into a crackling crust — the defining characteristic of excellent banana bread that is often absent from home recipes using granulated sugar.

Coffee and tea: The "Sugar in the Raw" packet (5g each) is turbinado, but demerara performs identically. The partial dissolution — large crystals take 45-60 seconds to fully dissolve in hot liquid — releases sweetness in stages rather than all at once, which some coffee drinkers prefer for controlling sweetness perception through the cup.

Storage and Clumping Prevention

Demerara's low moisture content (approximately 0.5-1% compared to brown sugar's 3-5%) means it is far more stable in storage than commercial brown sugar. It does not harden or clump under normal conditions because the residual molasses is not sufficient to absorb enough atmospheric moisture to bridge crystals together.

Store demerara in an airtight container at room temperature. Unlike brown sugar, it does not require a terra cotta disc or bread slice to maintain texture. Shelf life is effectively indefinite — sugar does not support microbial growth. The only quality degradation is possible moisture absorption in very humid environments, which can cause light clumping. Solution: spread on a baking sheet and dry in a 200°F (93°C) oven for 10-15 minutes, then cool and break apart any clumps.

If you see slight whitening on demerara crystals, this is "bloom" — sugar migration that occurs during temperature fluctuations. The crystals are still usable; the bloom is aesthetic only and the flavor is unaffected.
