Sugar in Baking
Sugar in baking does far more than sweeten. It keeps cakes moist, helps them brown, tenderises the crumb, whips air into butter, and preserves jams. It comes in many forms, from fine white sugar to golden demerara and soft brown sugar, and each one changes the taste and texture of a bake in its own way.

What it is
Baking sugars are mostly the same crystal in different dresses. Granulated sugar is the everyday workhorse; caster sugar is ground finer so it dissolves fast; icing sugar is powdered with a whisper of starch; and brown sugars carry molasses, which brings moisture and a toffee-like depth. Jaggery, India's unrefined cane sugar, adds an earthy, almost smoky sweetness of its own.
Why it matters
Sugar is a structural ingredient, not just a flavour. Creamed with butter, its sharp crystals carve out the tiny air pockets that make a cake light. It clings to moisture, keeping bakes soft for days, and it browns in the oven's heat to build colour and caramel flavour. Cut it back drastically and a cake bakes up pale, dry, and oddly bready.
Common mistakes
Swapping brown sugar for white changes more than colour: the molasses adds moisture and chew, which is lovely in cookies but can weigh down a delicate sponge. Icing sugar in place of caster leaves creamed butter flat, since there are no crystals to cut in air. And in a humid Bangalore kitchen, open sugar clumps and brown sugar turns to rock, so seal it well.

The difference between our fudgy brownies and a light celebration sponge lies partly in how each uses sugar, chosen for chew in one and airiness in the other.

Frequently Asked Questions
Can I reduce the sugar in a cake recipe?
A little, yes; a lot, no. Sugar carries moisture, tenderness, browning, and lift, so trimming it slightly usually goes unnoticed, but cutting it heavily leaves a cake dry, pale, and tough. If you want something less sweet, a recipe designed that way beats surgery on a classic one.
What is the difference between caster sugar and icing sugar?
Caster sugar is finely ground crystals that dissolve quickly yet still whip air into butter. Icing sugar is powdered until silky and usually contains a touch of starch to stop clumping, which suits frostings and dustings but makes it a poor partner for creaming.
Is jaggery a good substitute for sugar in baking?
It can be, with adjustments. Jaggery brings a deep, earthy sweetness and extra moisture, so it suits sturdy bakes like spice cakes and cookies better than airy sponges. It also browns faster, so bakes made with it tend to colour more deeply.
