Common Mistakes to Avoid

When making the Flourless Orange Pistachio Almond Cake, there are a few common pitfalls to watch out for. Avoiding these mistakes will ensure a delicious and successful dessert.

Skipping the orange boiling step: Boiling the oranges is crucial for softening them and enhancing their flavor. Make sure to cook them thoroughly before blending.
Not using finely ground nuts: Using coarsely ground almonds or pistachios can lead to an uneven texture. Opt for finely ground nut meals to achieve a smooth batter.
Overmixing the batter: Overmixing can lead to a dense cake instead of a light one. Mix until just combined after adding the eggs to keep it airy.
Ignoring baking time and temperature: Every oven is different; start checking your cake a few minutes before the recommended time. It should be golden and firm in the center when done.
Forgetting to grease the pan: A well-greased or lined pan prevents sticking. Don’t skip this essential step for easy removal of your cake.
