โญ Ground Flaxseed (mixed with water) (Best Fat-Free Option)
1 tablespoon ground flaxseed + 3 tablespoons water per 1 tablespoon cornstarchWhen mixed with water, ground flaxseed forms a mucilaginous gel that can act as a binder and thickener in quiche fillings. This gel helps stabilize the custard by trapping moisture and providing structure.
Prepare the flax gel ahead of time by mixing ground flaxseed with water and letting it sit for 5-10 minutes. Incorporate it evenly into the custard mixture. Be mindful that flaxseed can impart a mild nutty flavor and a slightly denser texture.
While not as neutral as cornstarch, flaxseed gel can improve the nutritional profile and provide a unique texture that some may find appealing in a rustic quiche.
