Common Mistakes to Avoid
When making Cod & Potatoes in Rosemary Cream Sauce, avoiding common mistakes can enhance your dish’s flavor and texture.
- Skipping the marination step: Marinating the cod with lemon juice and zest adds flavor. Don’t rush this step; let it sit while you prepare the pan.
- Overcooking the cod: Cod cooks quickly, so watch it carefully. Remove it from the pan as soon as it’s golden and flakey to avoid dryness.
- Not seasoning adequately: Underseasoning can lead to bland flavors. Taste and adjust salt and pepper throughout cooking for a more balanced dish.
- Ignoring sauce thickness: If your cream sauce isn’t thickening, simmer it longer. Patience will yield a rich, creamy consistency that coats the potatoes beautifully.
- Using cold ingredients: Cold cream or broth can shock the sauce. Warm them slightly before adding to ensure a smooth blend.
