Recipe Overview

Prep Time: 30 minutes
Cook Time: 20-30 minutes (+ up to 10 minutes if needed)
Total Time: 1 hour
Servings: 10
Yield: 1 cake
Dietary Type: Gluten-Free

Ingredients

1 1/2 cups pistachios, weighed without shells (225 grams)
1 cup sugar
3 large eggs, separated
2 teaspoons grated lemon zest
1/3 cup cornstarch (cornflour)
1 teaspoon baking powder, gluten-free if required for diet
1/2 teaspoon baking soda (bi-carb soda)
1/4 teaspoon salt

Equipment Needed

9 inch / 23 cm springform round baking pan
Large pot
Clean tea towel/kitchen towel
Food processor
Large bowl
Electric mixer or whisk
Wire rack

Instructions

Begin by preheating your oven to 350°F (180°C). Ensure the oven rack is positioned in the center for even baking.
Prepare your baking pan by thoroughly greasing a 9-inch (23 cm) springform round pan. This step is crucial to prevent the cake from sticking and ensuring easy removal later.
Next, prepare the pistachios. Bring a pot of water to a boil. Once boiling, plunge the pistachios into the water for a quick 30 seconds. This blanching process helps to loosen the skins for easier removal.
Remove the pistachios from the boiling water, drain them well, and then rub them dry with a clean tea towel or kitchen towel. The goal is to remove as much moisture as possible before peeling.
Peel off the pistachios’ skins. This can be a bit tedious, but it’s worth it for the smoother texture and more refined flavor in the final cake.
In a food processor, combine the cleaned pistachios and the sugar. Process until the mixture is finely chopped. You want a texture that resembles coarse almond flour. Be careful not to over-process, as the pistachios can release their oils and become pasty.
Transfer the pistachio and sugar mixture to a large bowl. Add the egg yolks, lemon zest, baking powder, cornstarch, baking soda (bicarb), and salt. Stir to combine all the ingredients until you have a smooth, even batter.
In a separate, clean bowl, beat the egg whites until stiff peaks form. This is best achieved with an electric mixer, but a whisk and some elbow grease will also do the trick. The stiff peaks are essential for creating a light and airy cake. Be careful not to overwhip the whites, as this can make them dry and difficult to fold in.
Gently fold the egg whites into the pistachio mixture. It’s crucial to fold gently to avoid deflating the egg whites, which would result in a dense cake. Use a spatula and work in sections, lifting the batter from the bottom of the bowl and folding it over the egg whites. Continue until just combined; a few streaks of white are okay.
Spoon the batter into the prepared baking pan, spreading it evenly.
Bake in the preheated oven for 20-30 minutes, or until the cake is cooked through. To check for doneness, insert a toothpick or fine skewer into the center of the cake. If it comes out clean, the cake is done. If not, place it back in the oven for up to another 10 minutes, checking every few minutes to avoid overbaking.
Once baked, cool the cake in the tin for 15 minutes. This allows the cake to set slightly and makes it easier to remove from the pan.
After 15 minutes, remove the cake from the tin and cool completely on a wire rack. This prevents the bottom of the cake from becoming soggy.

Expert Tips & Tricks

Toast the pistachios: For an even deeper, more intense pistachio flavor, lightly toast the pistachios in a dry pan over medium heat for a few minutes before processing them. Watch them carefully, as they can burn easily.
Lemon Zest Power: Don’t skimp on the lemon zest! It brightens the nutty flavor and adds a lovely aroma to the cake.
Folding Technique: Mastering the folding technique is key for a light and airy cake. Avoid stirring or mixing vigorously, as this will deflate the egg whites.
Preventing a Soggy Bottom: Ensure the cake is completely cool on a wire rack before serving or storing to prevent moisture buildup.
Even Baking: If your oven tends to bake unevenly, rotate the cake halfway through the baking time to ensure even browning.

Serving & Storage Suggestions

This gluten-free pistachio cake is wonderful served plain with a cup of coffee or tea. For a more elegant presentation, dust it with powdered sugar or top it with a simple glaze made from powdered sugar and lemon juice. It also pairs beautifully with fresh berries, such as raspberries or strawberries.

Store any leftovers in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. You can also freeze the cake for up to 2 months. Thaw it overnight in the refrigerator before serving. To refresh the cake, you can gently warm it in a low oven or microwave for a few seconds.

FAQs (Frequently Asked Questions)

Q: Can I use pre-shelled pistachios?
A: Yes, you can use pre-shelled pistachios, but be sure to check them for freshness and quality. Weigh them after shelling to ensure you have the correct amount (225 grams or 1 1/2 cups).

Q: Why do I need to blanch the pistachios?
A: Blanching the pistachios helps to loosen the skins, making them easier to remove. Removing the skins results in a smoother texture and more refined flavor in the cake.

Q: Can I use a different type of sugar?
A: While granulated sugar is recommended, you can experiment with other types of sugar, such as caster sugar or brown sugar. Brown sugar will impart a slightly different flavor and a moister texture.

Q: My cake sank in the middle. What went wrong?
A: A sunken cake can be caused by several factors, including overmixing the batter, opening the oven door too frequently during baking, or not having the oven at the correct temperature. Ensure you fold the egg whites gently and avoid opening the oven door unnecessarily.

Q: How can I tell if the cake is fully cooked?
A: The best way to check for doneness is to insert a toothpick or fine skewer into the center of the cake. If it comes out clean, the cake is done. If not, place it back in the oven for a few more minutes and check again.
