Published in Garten's 2012 cookbook "Make It Ahead," this recipe uses lemon juice, zest, syrup, and a lemon glaze for an intensely flavorful and wonderfully moist dessert.
Garten calls for four to five large lemons' worth of juice and a ⅓ cup of lemon zest, plus buttermilk for a tender texture and lemon juice and sugar syrup to soak the cake.
Finally, Garten mixes powdered sugar with lemon juice to make a glistening glaze. This is drizzled atop the finished poppyseed cake for the perfect final touch.
