}Explanation
Convert caster sugar teaspoons to grams with an ingredient-specific teaspoon reference derived from the shared cup basis.
The gram result stays more consistent than a generic teaspoon chart. That is especially useful for baking, syrups, and dessert prep where sweetness and structure depend on repeatable weight. Caster Sugar can vary with crystal size, moisture, and caking, so the page keeps one explicit basis instead of mixing packing styles.
