Garlic: The Comprehensive Guide

1. History of Garlic:

Garlic, Allium sativum, has a history stretching back thousands of years. Originating in Central Asia, it was cultivated as far back as 5000 BC. Its use spread rapidly, becoming a staple in ancient Egypt, Greece, and Rome. Egyptians revered garlic for its believed medicinal properties and used it to boost the strength of labourers building the pyramids. Greeks and Romans employed garlic for culinary and medicinal purposes, believing it enhanced strength, stamina, and even protected against evil spirits. Throughout history, garlic has played a role in various cultures, both as a food and a medicine. (Source: National Geographic)

2. Cooking Techniques:

Garlic is incredibly versatile and can be cooked in numerous ways to enhance different flavours.

• How to cook garlic (general overview): The cooking method significantly impacts garlic’s flavour. Raw garlic offers a sharp, pungent bite. Cooking mellows its intensity, releasing a sweeter, more complex taste. Avoid burning garlic as this will make it bitter.

• How to prepare garlic for cooking: Before cooking, you'll need to prepare the garlic. See Section 3 for detailed instructions.

• How to grill garlic: For grilling, wrap whole, unpeeled garlic bulbs in foil with olive oil and herbs like rosemary or thyme. Grill over medium heat for 30-40 minutes until soft. Alternatively, grill individual cloves after peeling and tossing in oil. They take about 5-10 minutes.

• How to bake garlic: Roasting garlic softens it and concentrates its sweetness. Wrap a whole bulb (trimmed at the top) in foil, drizzle with olive oil, and bake at 200°C (400°F) for 45-60 minutes, or until soft and caramelised. You can then squeeze the softened garlic from the cloves.

• How to sauté garlic: Sautéing garlic is a common method to add flavour to dishes. Heat olive oil or butter in a pan over medium heat. Add minced garlic and cook for about 30 seconds to 1 minute, or until fragrant and lightly golden. Be careful not to burn it, as this makes it bitter.

3. Ingredient Preparation:

Proper preparation is crucial for achieving the desired flavour and texture.

• How to cut garlic: You can cut garlic into slices, which is good for adding to stir-fries or roasting. Ensure you have a sharp knife.

• How to peel garlic: There are several methods. The easiest is to place the garlic clove on a cutting board, place the flat side of a large knife over it, and gently but firmly press down. The skin should crack, making it easier to peel. You can also shake the cloves in a container or between two bowls.

• How to dice garlic: After peeling, mince the garlic finely with a knife. This is suitable for sauces and dressings.

• How to mince garlic: Mincing involves chopping the garlic into very small, fine pieces. This maximises flavour diffusion. Use a sharp knife and rock it back and forth over the garlic to achieve a fine mince.

4. Storage:

Proper storage extends garlic's shelf life and preserves its flavour.

• How to store garlic (short-term): Store unpeeled garlic bulbs in a cool, dark, and dry place with good air circulation. Avoid storing garlic in the refrigerator unless it’s been peeled, as the humidity can cause it to sprout or rot. A mesh bag or a container with air holes is ideal.

• How to store garlic (long-term): For long-term storage, you can freeze peeled or minced garlic. Place minced garlic in an ice cube tray with olive oil or water and freeze. Once frozen, transfer to a freezer bag. Alternatively, you can dry garlic cloves or make garlic powder.

• How long does garlic typically last under different storage conditions? Whole, unpeeled garlic bulbs can last for several months (up to 6 months) when stored correctly. Peeled garlic cloves stored in the refrigerator last for up to 2 weeks. Frozen garlic can last for several months.

5. Substitutions:

If garlic is unavailable or you have an allergy, there are several suitable substitutes.

• What are good substitutes for garlic?
  • Garlic powder: Provides a similar, though less intense, flavour.
  • Garlic paste: A good substitute, offering similar flavour intensity.
  • Garlic-infused oil: Can be used to add garlic flavour to dishes.
  • Onion: Offers a similar allium base. For a comparable sharpness, use raw onion and for a mellower flavour, use cooked.
  • Shallots: These have a milder flavour than garlic but still provide that distinctive allium taste.
  • Asafoetida: A dried resin from a plant, used in Indian cuisine, and has a strong garlic-like flavour, but it is best used with a small amount as it is very pungent.
