Lemons
Lemons are an acidic tree fruit, with a sharp, bright flavor and are a powerful ingredient in a cooks arsenal. Both the juice and peel are used in a wide range of dishes. Pickling is also common, with preserved lemons being particularly prized for their intense savory, salty-sour flavor in Moroccan cooking.
Lemon juice can serve multiple functions; it can be added to milk to raise its acidity and make it curdle - which is how the Indian cheese paneer is produced. It also helps to denature proteins, which is why it's often used to tenderize meat in marinades by breaking down connective tissue.
In salad dressings it can also be used to aid emulsifiers, such as mustard and honey, by suspending the oil in the lemon juice, which helps to coat salad ingredients more evenly.
The fragrant lemon zest (the outer peel) and is often grated over finished dishes to add brightness and is commonly used in baked goods like cakes, muffins, and biscuits, as well as in marinades and spice rubs.
Preparation
Lemons can be zested with a lemon zester. The aromatic zest can then be used in various dishes.
To use the juice, cut the lemon in half and squeeze, ensuring to catch and discard all the pips. Juicing can also be done with a lemon juicer.
It's also possible to make preserved lemons by submerging them in a mixture of salt and lemon juice and leaving them to cure for 4-6 weeks. Once ready they can be stored in the fridge for several months. To use simply chop the lemons and use them in your tagines, salads dressings or mix through mashed potato.

Can you use lemons directly from the tree?
Yes, lemons are generally safe to use from the tree. Some ornamental lemon trees are sprayed with chemicals, and you should not eat the sprayed lemons. It's best to wash any lemons before consuming them to remove any pollution or pesticides.
