## Cooking with Aluminum Foil: Best Practices

Aluminum foil is a valuable tool in the kitchen, but proper usage is crucial for safety and optimal cooking results. Here’s a breakdown of various cooking applications:

### 1. Baking

* **Lining Baking Sheets:** Lining baking sheets with aluminum foil simplifies cleanup and prevents food from sticking. For best results, use heavy-duty foil and ensure it completely covers the pan, extending slightly over the edges. This creates a barrier that protects the pan from baked-on residue.

* **Reynolds Recommendation:** Reynolds recommends using their heavy-duty foil for lining baking sheets, especially when baking sticky or messy items like cookies, brownies, or roasted vegetables. This ensures easy removal and effortless cleanup.

* **Covering Baked Goods:** Covering baked goods with aluminum foil during baking can prevent over-browning. If your pie crust or casserole is browning too quickly, gently tent a sheet of foil over the top. This will deflect heat and allow the inside to cook evenly without burning the surface.

* **Reynolds Recommendation:** Reynolds suggests loosely tenting the foil to allow steam to escape, preventing the baked goods from becoming soggy. Avoid tightly wrapping the foil, as this can trap moisture and alter the texture.

* **Baking in Packets (En Papillote):** Creating foil packets is a fantastic way to steam food in the oven, locking in moisture and flavor. This method is particularly well-suited for fish, vegetables, and poultry.

* **Reynolds Recommendation:** To create a foil packet, place your ingredients in the center of a large sheet of aluminum foil. Bring the edges together and fold them over several times to create a tight seal. Leave some room inside the packet for steam to circulate. You can add herbs, spices, and a drizzle of olive oil or broth to enhance the flavor.

### 2. Grilling

* **Grilling Delicate Foods:** Grilling delicate foods like fish or vegetables directly on the grill grates can be challenging, as they tend to stick and fall apart. Aluminum foil provides a protective barrier, preventing sticking and ensuring even cooking.

* **Reynolds Recommendation:** Reynolds suggests using heavy-duty foil for grilling. Lightly grease the foil with cooking oil or spray to further prevent sticking. Place the food on the foil and grill as usual. You can also create foil packets for grilling, similar to baking en papillote.

* **Protecting Grill Grates:** Covering grill grates with aluminum foil can help prevent flare-ups and make cleanup easier. Poke a few holes in the foil to allow smoke and heat to circulate. This method is particularly useful when grilling fatty foods that tend to drip and cause flare-ups.

* **Reynolds Recommendation:** Reynolds advises against completely covering the grill grates with foil, as this can restrict airflow and affect the grilling process. Only cover the portion of the grates where the food will be placed.

* **Indirect Grilling:** Using aluminum foil to create an indirect grilling zone can help cook large cuts of meat evenly. Place a sheet of foil over one side of the grill grates, creating a barrier between the food and the direct heat source. This allows the meat to cook slowly and evenly, preventing it from burning on the outside while remaining raw on the inside.

### 3. Roasting

* **Lining Roasting Pans:** Lining roasting pans with aluminum foil simplifies cleanup and prevents baked-on grease and residue. Use heavy-duty foil and ensure it completely covers the pan, extending over the edges.

* **Reynolds Recommendation:** Reynolds recommends using their heavy-duty foil for lining roasting pans, especially when roasting fatty meats like poultry or pork. This makes cleanup a breeze and protects your roasting pan from damage.

* **Covering Roasts:** Covering roasts with aluminum foil during the initial stages of cooking can help retain moisture and prevent the meat from drying out. Remove the foil during the last 30-60 minutes of cooking to allow the roast to brown and crisp.

* **Reynolds Recommendation:** Reynolds suggests tenting the foil loosely over the roast to allow steam to escape. Avoid tightly wrapping the foil, as this can trap moisture and prevent the roast from browning properly.

### 4. Microwave Use (with Caution)

While aluminum foil is generally not recommended for microwave use due to the risk of sparking and fire, there are a few limited exceptions.

* **Shielding Thin Areas:** Small strips of aluminum foil can be used to shield thin areas of food, such as the tips of chicken wings or drumsticks, to prevent them from overcooking in the microwave. However, this should be done with extreme caution and only when necessary.

* **Reynolds Recommendation:** Reynolds strongly advises against using aluminum foil in the microwave unless absolutely necessary. If you must use it, ensure the foil is smooth, flat, and tightly pressed against the food. Do not allow the foil to touch the sides or top of the microwave oven, and monitor the microwave closely while it’s running. Never use crumpled or wrinkled foil in the microwave.

## Storing Food with Aluminum Foil: Maintaining Freshness

Aluminum foil is an effective barrier against light, moisture, odors, and bacteria, making it an excellent choice for storing food. However, proper techniques are essential to maximize its effectiveness.

### 1. Wrapping Leftovers

* **Wrapping Solid Foods:** Wrap leftovers tightly in aluminum foil to prevent them from drying out and absorbing odors from the refrigerator. Ensure the foil is securely sealed around the food to create an airtight barrier.

* **Reynolds Recommendation:** Reynolds suggests using their regular or heavy-duty foil for wrapping leftovers. For optimal freshness, wrap the food while it’s still slightly warm to prevent condensation from forming inside the foil.

* **Wrapping Sandwiches and Snacks:** Aluminum foil is ideal for wrapping sandwiches, snacks, and other portable food items. It keeps them fresh and prevents them from getting crushed in lunchboxes or bags.

* **Reynolds Recommendation:** Reynolds offers pre-cut foil sheets that are perfectly sized for wrapping sandwiches and snacks. These sheets are convenient and easy to use.

### 2. Covering Dishes

* **Covering Bowls and Plates:** Aluminum foil can be used to cover bowls and plates of leftovers, keeping them fresh and preventing spills in the refrigerator.

* **Reynolds Recommendation:** Reynolds suggests using their heavy-duty foil for covering dishes, as it’s more durable and less likely to tear. Ensure the foil is tightly sealed around the edges of the dish to create an airtight barrier.

* **Preventing Oven Splatter:** When reheating dishes in the oven, covering them with aluminum foil can prevent splattering and make cleanup easier. This is particularly useful when reheating sauces or dishes that tend to bubble.

### 3. Freezing Food
