It's almost fresh zucchini season, so it's definitely time to use up that last two cups of the frozen grated zucchini from last year's avalanche of zukes. While the zucchini seems to thaw to a puddle of green-flecked water, it bakes up fine and adds much-needed moisture to gluten-free concoctions. I recommend the cardamom in this recipe.
1 cup brown rice flour
3/4 cup amaranth flour
1/2 cup potato starch
1/4 cup tapioca starch
1/2 tsp xanthan gum
1 tsp gelatin
2/3 cup brown sugar
2 tsp (rounded) baking powder
1 tsp baking soda
1/2 tsp ground cardamom or cinnamon
1/4 tsp salt
2 cups grated zucchini
1/2 cup butter, melted
1/4 cup milk
3 eggs
2 tsp grated orange rind
1 cup chopped walnuts
Glaze:
1/4 cup gluten-free icing sugar
2 tsp orange juice
Line loaf pan with parchment paper or grease. Set aside.
Whisk together flours, sugar, baking powder and soda, cardamom, and salt. In a separate bowl, whisk together zucchini, butter, milk, eggs, and orange rind. Pour wet ingredients over flour mixture. Sprinkle with walnuts and stir just to combine. Pour into prepared pan. Bake at 350F until tests clean, about 1 hour. Let cool in pan for 15 minutes. Turn out on a rack to cool completely.
Combine icing sugar and orange juice to make glaze. Brush over hot loaf. Let cool.
