This tart combines heritage flours (einkorn, kamut, rye), cold butter, and apple cider vinegar for the crust. The filling uses seasonal fruits, low-sugar pectin, honey, lemon juice, and warm spices. It's finished with an egg wash and demerara sugar for a crisp, golden crust.
Learn how to cook Heritage Grain Crust with Temperature-Controlled Fruit Setting Recipe by first making a flaky crust with ancient grains, then preparing fruits with the precise 85°C temperature technique that activates pectin without overcooking. Bake at 200°C initially, then reduce to 180°C, creating a galette with perfectly set fruit that's neither runny nor too stiff.
Temperature control is crucial because heating fruit with pectin to exactly 85°C activates the setting agent without overcooking the fruit. This precision preserves the fresh flavour and texture of the fruit while ensuring it sets properly—avoiding both a runny mess and an overly stiff, jam-like consistency.
Yes, you can substitute all-purpose flour, though you'll lose the nutty complexity that heritage grains provide. For a closer match, use 180g all-purpose flour combined with 45g whole wheat flour. You may need slightly less water as heritage grains typically absorb more moisture.
Prevent soggy bottoms by preheating a baking stone or heavy sheet in the oven, properly activating pectin in your fruit filling, allowing fruit to cool slightly before adding to the dough, and creating adequate dough folds around the edges to contain juices during baking.
