🥬 1. Steaming Vegetables

Steaming is a gentle cooking method that uses hot vapor to cook vegetables, minimizing nutrient loss and retaining their natural color and crunch.

Advantages and Disadvantages

Advantages:

1. Preserves water-soluble vitamins (e.g., Vitamin C, B vitamins).
2. Retains natural color and crisp texture.
3. Requires minimal to no added fat.

Disadvantages:

1. Can sometimes result in bland flavor if not seasoned properly.
2. Not suitable for all vegetable types (e.g., dense root vegetables may require longer steaming).
3. Requires specific equipment (steamer basket).

Example Recipe: Steamed Broccoli with Lemon and Garlic

This recipe showcases how steaming can transform simple ingredients into a flavorful side dish.

Ingredients:

1. 1 head of broccoli, cut into florets (approximately 500 grams)
2. 2 cloves of garlic, minced
3. 1 lemon, juiced and zested
4. 2 tablespoons of olive oil
5. Salt and black pepper to taste
6. Optional: red pepper flakes for a spicy kick

Steps:

1. Fill a pot with about 2 inches of water and bring to a boil. Place a steamer basket inside.
2. Add broccoli florets to the basket in a single layer. Cover and steam for 5-7 minutes.
3. While steaming, prepare dressing: whisk garlic, lemon juice, zest, olive oil, salt, and pepper.
4. Transfer cooked broccoli to a bowl and immediately drizzle with dressing. Toss to coat.
5. Serve immediately as a side dish or over quinoa.

Tips: Avoid over-steaming. For variation, add toasted almonds or sesame seeds.
