Aromatic bases & spice pastes
Ginger–Garlic Paste
अदरक-लहसुन पेस्ट · A finely ground, moist paste made from fresh ginger and fresh garlic, used as a fundamental aromatic base in South Asian, Southeast Asian, and East Asian cuisines. It delivers a concentrated, balanced heat and fragrance that mellows and melds into dishes during cooking.
The formula
1 part ginger : 1 part garlic (by weight)
Add ½–1 % salt (≈ 2 g per 200 g total) and just enough cold water (5–10 % of total weight) to facilitate grinding; optional thin film of neutral oil on the storage surface.
Identity
- Must be made from raw, fresh ginger and fresh garlic
- Proportion must be 1 : 1 by weight (within ±10 % for personal taste)
- No added fats or acids are essential; salt is optional but recommended for texture
- Ground to a smooth, homogeneous paste – no visible fibers
- Refrigerated immediately after preparation
Ingredients
| Base | Fresh ginger (peeled) | Use firm, bright ginger; old ginger is woody and less aromatic. |
| Base | Fresh garlic (cloves, peeled) | Select plump, tight‑skinned cloves for maximum allicin. |
| Binder | Salt (fine) | A pinch (≈1 % of total weight) helps break cell walls and preserves color. |
| Liquid | Water (cold) | Added in small amounts to enable a smooth grind in a mortar or processor. |
| Fat | Neutral oil (e.g., sunflower) | Optional thin layer on top of stored paste to retard oxidation. |
Method
- 1Peel the ginger and garlic.The papery skin and any blemishes contain bitter compounds and impede smooth grinding.
- 2Roughly chop the peeled ginger and garlic into 1–2 cm pieces.Smaller pieces increase surface area, making the grinding faster and more even.
- 3Add the chopped ingredients to a heavy‑bottomed mortar (or a small food processor). Sprinkle with salt.Salt’s ionic strength weakens pectin networks, aiding the release of aromatic oils.
- 4Grind, adding water a teaspoon at a time, until a smooth, uniform paste forms.Water acts as a lubricant and carrier, allowing the cell contents to mix into a cohesive paste without overheating.
- 5Taste and adjust seasoning; optionally stir in a few drops of oil.A finishing touch of oil seals the surface and slows oxidation during storage.
- 6Transfer to a clean, dry glass jar, press a thin layer of oil on top, seal, and refrigerate.An oil cap creates a barrier to oxygen, extending shelf life.
Techniques that matter
Wet grinding
Continuous addition of liquid prevents the paste from drying out and allows the fibrous ginger to break down into a smooth consistency.
Abrasive crushing (mortar & pestle)
The mechanical shearing ruptures ginger’s oleoresin cells, releasing volatile oils (gingerols) and allicin from garlic.
Salt‑mediated extraction
Sodium ions weaken pectin cross‑links, softening the matrix and extracting more flavor compounds.
Oil‑capped storage
A thin oil layer limits exposure to air, reducing enzymatic browning and oxidation of allicin.
Variations & derivatives

Often includes lemongrass, kaffir lime zest, and a splash of fish sauce; used in Thai curries and soups.

Prepared with a spoonful of mustard oil added after grinding; imparts a pungent, nutty note common in fish curries.

Substitutions
- Fresh ginger → Ground ginger (powder) — Powder lacks the fresh volatile oils; use ¼ amount (by weight) and rehydrate with water.changes result
- Fresh garlic → Garlic powder or pre‑minced garlic — Powdered garlic is less aromatic and has a different texture; substitute at ½ amount.changes result
- Salt → Soy sauce (for umami) — Adds saltiness plus umami, but introduces liquid; reduce additional water accordingly.
- Water → Citrus juice (lime/lemon) — Adds acid that brightens flavor but may alter the paste’s pH; use sparingly.
Troubleshooting
Paste turns brown or grey within a day
Oxidation of phenolic compounds when exposed to air; insufficient salt or oil barrier. → Stir in a pinch more salt, press out any air pockets, and seal with a thin oil layer before refrigerating.
Paste is watery and separates
Too much water added during grinding; over‑dilution. → Drain excess liquid through a fine sieve, then re‑grind with a little extra ginger to re‑thicken.
Gritty or fibrous texture
Insufficient grinding; ginger fibers not fully broken down. → Continue grinding in the mortar or use a small food processor; add a few drops of water to help the blade shear the fibers.
Bitter aftertaste
Residual ginger skin or burnt garlic during sautéing. → Ensure all skin is removed; if sautéing the paste, cook over low heat, stirring constantly.
