Maple Syrup (Best Option)
1 tablespoon per 1 tablespoon brown sugarMaple syrup is a liquid sweetener with a flavor profile that includes subtle caramel and woody notes, similar to brown sugar's molasses content. This makes it an excellent substitute in dishes like frittata where a gentle sweetness is desired without overpowering savory elements.
When using maple syrup, reduce other liquids slightly to compensate for its moisture content. Stir it well into the egg mixture to ensure even distribution and prevent localized sweetness.
The final frittata will have a slightly more moist texture and a nuanced sweetness that complements vegetables and cheese, closely mimicking the effect of brown sugar.
