Blanch broccoli for 3 minutes, asparagus for 2-4 minutes (depending on thickness), and carrots for 2-5 minutes (depending on size and cut). This process helps preserve their color, texture, and nutrients.
Detailed Explanation:
Blanching involves briefly immersing vegetables in boiling water, followed by an ice bath to stop the cooking process. The timing is crucial to achieve the desired results:
- Prepare the Vegetables: Wash and cut the vegetables into uniform sizes. This ensures even blanching.
- Boil Water: Bring a large pot of water to a rolling boil.
- Blanch Broccoli: Add broccoli florets to the boiling water and blanch for 3 minutes.
- Blanch Asparagus: Add asparagus spears to the boiling water. Thin spears need 2 minutes, medium spears 3 minutes, and thick spears 4 minutes.
- Blanch Carrots: Add sliced or diced carrots to the boiling water. Small pieces need 2 minutes, while larger pieces may require up to 5 minutes.
- Ice Bath: Immediately transfer the blanched vegetables to an ice bath (a bowl filled with ice and water) to stop the cooking process. This preserves their color and texture.
- Drain and Dry: Once cooled, drain the vegetables thoroughly and pat them dry before freezing or using them in recipes.
Pro Tip:
Don't overcrowd the pot when blanching. Blanch in batches to maintain the water temperature and ensure even cooking. Overcrowding lowers the water temperature, leading to unevenly blanched vegetables.
