Conversion and rationale

Original sweetener (classic version): 100 g white sugar + 30 ml honey

Conversion used: Use 100 ml maple syrup total (80 ml in custard, 20 ml glaze); omit honey; reduce milk by 30 ml to prevent overflow from syrup's moisture; bake at 370°F (−5°F from 375°F) to prevent phyllo charring from syrup's darker caramelization.

Why Quebec maple syrup: Maple's wood notes amplify walnut earthiness; Quebec terroir pairs naturally with indigenous North American walnuts. Mineral-rich syrup (manganese) supports walnut polyphenol absorption.

General rule: 1 cup (250 ml) sugar ≈ 3/4 cup (180 ml) maple syrup; reduce liquids by 45–60 ml per cup of syrup and lower oven by 15 °C. Substitution calculator →
