Simo and Cicci Recommend

You can store the invisible zucchini and salmon cake in the fridge well sealed in an airtight container for up to three days.

For a lactose-free version, use lactose-free milk or a plant-based beverage.

You can replace rosemary with other herbs such as thyme, marjoram, oregano, or chives.

If you like, you can enrich the cake batter with cheese cubes like smoked cheese or emmental.

You can also use an air fryer, cooking the cake at 392°F for about 35 minutes.
