Honey (Best Option)
1 tablespoon honey per 1 tablespoon maple syrupHoney works well as a substitute because it has a comparable sugar content and thickness, which helps maintain the moisture and texture of the quiche custard. The natural sugars in honey caramelize similarly during baking, preserving the flavor balance.
When using honey, ensure it is well incorporated into the custard mixture to avoid uneven sweetness. Slightly reduce other liquids if the honey is particularly runny to maintain the custard's consistency.
The final quiche will have a subtly different aroma and a slightly richer sweetness, but the texture and overall balance will remain close to the original recipe.
