Common Mistakes to Avoid

When making Flourless Orange Pistachio Almond Cake, it’s easy to overlook some details. Here are common mistakes to avoid for the best results.

Not boiling the oranges enough – Ensure you boil the oranges for at least 30 minutes. This softens them, allowing for a smooth puree that enhances flavor.
Skipping the blending step – Blending the boiled oranges into a smooth puree is crucial. If you skip this, your cake may have an uneven texture and lack the vibrant orange flavor.
Incorrect egg mixing – Whisk the eggs until frothy before adding them to the mixture. This step incorporates air, resulting in a lighter cake.
Overbaking – Keep an eye on your cake during baking. If it’s overbaked, it can become dry. A toothpick test should show moist crumbs but not wet batter.
Not letting it cool properly – Allowing the cake to cool in the pan helps it set correctly. If you transfer it too soon, it may crumble or break apart.
