Garlic
Learn the culinary uses, pH levels, and storage qualities of garlic for everyday cooking.
Classification: Allium sativum
pH Level: 5.3 - 6.3 (Mildly acidic)
A pungent, sulfur-rich allium bulb central to savory depth across global cuisines.
Common Culinary Roles
- ⯅Aromatic foundation for stir-fries, stews, and sautéed greens.
- ⯅Roasted whole to develop sweet, caramelized notes.
- ⯅Emulsified raw in classic sauces like aioli and toum.
Storage Guidelines
- ▪Store whole bulbs in a cool, dry, dark, well-ventilated location.
- ▪Avoid plastic bags or airtight containers which trap humidity and promote mold.
- ▪Do not refrigerate whole garlic, as cold temperatures stimulate sprouting.
Cooking Behavior & Heat Reactions
When heated, garlic's cellular structure breaks down, releasing alliinase which creates allicin. Under high dry heat (above 300°F / 150°C), garlic's high fructan (sugar) concentration and low moisture content cause it to scorch rapidly, turning bitter and black. Gentle heat extraction (blooming) in oil distributes culinary flavor compounds safely.

Cooking Standards FAQ
Q:Why does garlic turn blue or green sometimes?
This is a harmless chemical reaction. When raw garlic is combined with an acid (like vinegar or lemon juice), the sulfur compounds in the garlic react with natural amino acids to form polypyrrole pigments, turning blue-green.
Q:How does mincing garlic compare to using whole cloves?
Mincing garlic ruptures more cells, releasing maximum alliinase for a sharp, intense flavor. Whole crushed cloves release a mild, sweet aroma since fewer cell walls are disrupted.
