Honey (Best Option)
3/4 teaspoon per 1 teaspoon granulated sugarHoney works well as a sugar substitute in a frittata because it dissolves easily and integrates smoothly with the egg mixture, contributing both sweetness and moisture. Its natural enzymes can also slightly tenderize the eggs.
When using honey, reduce any additional liquid slightly to compensate for its moisture content. Be mindful of the slightly lower sweetness intensity compared to granulated sugar and adjust accordingly.
The final frittata will have a subtle, nuanced sweetness and a slightly moister texture, which can enhance the overall mouthfeel without overpowering the savory ingredients.
