Adjust oven rack to the middle position and preheat to 325°F. Grease a 9” x 5” loaf pan and set aside.
In a large mixing bowl, whisk to combine the oil and sugar. Add the eggs and whisk well. Add the milk, rose water, baking soda, advieh, and salt, and whisk to combine. Stir in the zucchini and pistachios, if using, with a large spoon, then fold in the flour until combined.
Pour the batter into the greased loaf pan and sprinkle lightly with additional brown sugar and advieh.
Bake for 55 to 60 minutes, or until the internal temperature registers 195°F (you can also test with a toothpick). Let the bread cool in the loaf pan for 10 minutes, then transfer it to a wire rack to cool for 20 minutes before slicing it with a sharp, serrated knife.
Store it in the refrigerator for 5 to 7 days or in the freezer for up to 3 months or so.
Oil: I used extra-virgin olive oil in one version and vegetable oil in the second. I think the olive oil made it a bit more savory, which was nice, but either one works. You could also use coconut oil (unrefined won't lend much flavor to the final product).
Sweetener: I used honey in the first version but found the flavor too bold (this largely depends on the intensity of your honey). I switched to brown sugar in the second version but you could use maple syrup, granulated sugar, or agave nectar. I also tried to reduce the sugar to 1/3 cup in one version but the flavor was flat. The little bit of extra sugar is well worth it.
Rose water: the amount called for in the recipe just gives a hint of floral aroma. You could always bump it up to 1 tsp if you want a bit more to come through.
Squash amount: the original recipe calls for 1-1/2 cups of squash but I packed even more in with 2 cups. I think that is approaching the max amount the bread can hold but maybe you can get in even more (it's like the kitchen version of double dare).
Flour: you could try whole wheat, spelt, rye or any number of your favorite flours in this recipe. Also try combining 1/2 all-purpose with 1/2 of another. Each will lend a slightly different flavor.
Preheat your waffle iron. All waffle irons are different, but I use an electric one and set it to a uniform texture at almost the highest darkness level because I like the crispness. Play around with your settings to see what you like best.
If you intend on using a flax egg, start by making that first. Whisk together 1 tablespoon ground flaxseed meal with 2.5 tablespoons of water and set aside for 5 minutes until thickened.
In a medium mixing bowl, whisk together flours, almond meal, sliced almonds, cinnamon, baking powder, salt and pepper. In a large mixing bowl, whisk together the egg, milk, brown sugar, agave, oil, turmeric and ginger. Fold the dry ingredients the wet ingredients until just combined.
Pour about 1/3 cup of the batter in the waffle iron and cook according to the manufacturer's instructions. Transfer cooked waffles to a cooling rack to cool slightly before eating and repeat with remaining batter. Transfer any uneaten waffles to an air-tight bag and refrigerate for a week. Alternatively, freeze waffles in a single layer until frozen through and transfer to a plastic ziplock bag. Use within a couple months.
The list of ingredients is lengthy, which is why I typically measure out and combine all of the dry ingredients the night before. I also combine all of the wet ingredients except the eggs, turmeric and ginger.
You can make a number of substitutions in this recipe:
Use all oat flour or all all-purpose
Leave out the sliced almonds
Use a chicken egg instead of a flax egg
Different types of milk can be used in place of the almond milk
Adjust the oven rack to the middle position and preheat the oven to 350°F. Spray an 8" tart pan with non-stick cooking spray and set aside.
Whisk together the flours and salt in a medium mixing bowl and set aside.
Using a hand or stand mixer, beat the sugar and butter together until fully incorporated and airy, about 1 minute. Add the rosemary, lavender, lemon zest, vanilla and salt to the sugar and butter and mix until incorporated. With the mixer running, slowly add the flour over low speed until just incorporated, scraping down the sides of the bowl as needed. There should be clumps of dough at this point.
Pour the mixture into the prepared tart pan and press down lightly with your hand to smooth the surface. The bottom side of a measuring cup is another good way to pat down the surface. Using the tines of a fork and pressing down so you hear the metal tap against the pan, prick lines of holes in the dough to create a dozen wedges. Finish by pressing the bottom of the tines horizontally around the edges of the dough.
Bake for about 23 minutes or until the edges have just started to turn golden but the center is still pale. Remove from the oven and allow to cool for a few minutes. Then, using a knife or bench scraper, cut the shortbread along the pricked lines. Allow to cool a bit more in the pan and then carefully lift the pieces out using a spatula or cake server and transfer to a wire rack to cool completely.

You can omit the rice flour and use 1 cup plus 2 tablespoons all purpose flour
