Never use aluminium foil with this type of food

ALUMINIUM foil is perhaps one of the most multipurpose tools in your kitchen. You can cook with foil. You can wrap leftovers with foil. You can use foil to prevent pie crusts from burning, keep casseroles warm before serving, and even clean various kitchen appliances and tools.

Honestly, having a roll of aluminium foil sitting around is the best thing you can do for your future self, because you’ll likely need it for one thing or another eventually. 

However, while foil is certainly multipurpose, it’s not all-purpose. There are a few instances, especially when dealing with certain kinds of foods, where you should avoid using aluminium foil.

Why You Shouldn’t Use Foil With Acidic Ingredients

Shiny silver foil might be the first thing you reach for when cooking, baking, or wrapping up leftovers, but pull your hand back if you’re working with a dish with a lot of citrus, vinegar, or even tomatoes. Using foil with high-acidity foods can have several consequences for both the food and the foil, including affecting the taste. 

When you put a lot of effort into a meal, the last thing you want is for it to end up tasting like the foil you cooked it on or wrapped it in. But when acid meets aluminium foil, that’s exactly what happens. Foil makes acidic foods oxidise faster, which can make food taste slightly metallic or acrid.

Beyond flavour disruption, acidic foods can also slightly break down foil, causing juices or liquids to leak onto your fridge shelves or into your baking pan, defeating the purpose of foil to begin with. Moreover, aluminum is more likely to leach into acidic foods than non-acidic foods. It’s not a significant amount, so don’t panic if you’ve used acidic ingredients with foil before. But it’s certainly something to keep in mind in the future. 

Use Parchment Paper Instead of Foil

If you’re looking for an alternative to foil, parchment paper—not to be confused with wax paper—is a great option. It’s just as convenient, can handle high temperatures, and won’t negatively interact with acidic meals or ingredients. Plus, it won’t impact flavour, and there’s no reason to worry about spillage or leaching.

Bottom line, it’s not a bad idea to keep both parchment paper and aluminum foil in your kitchen. Different wraps work for different things, so having both on hand helps you cook and store all kinds of foods safely.
