My Oma & I combined her Nusskuchen recipe and my DD's egg-free diet to create this lovely, dense macaroon/biscotti-type dough. The original German "nutcake" recipe calls for no less than 7 eggs, which we substituted here w/7x 1 Tbsp flax : 3 Tbsp water. Our hesitation was replaced by an eagerness to "mach es noch ein mal!", which I've done tonight, this time taking the time to convert the European measurements. Enjoy!
