1. Choose high-quality flaxseed oil: High-quality flaxseed oil has a higher content of omega-3 fatty acids and is of better quality. The fishy smell is relatively less.

2. Control the oil temperature: During the cooking process, try to keep the pot temperature at 150-180°C and avoid excessive temperatures to reduce the production of fishy smell.

3. Combination with other oils: Flaxseed oil can be mixed with other oils (such as olive oil, peanut oil, etc.) to reduce its sensitivity to fishy smell.

4. Add ingredients: When cooking, you can add some ingredients that can remove the fishy smell, such as ginger slices, green onions, garlic, etc., to reduce the fishy smell.
