Getting to Know Kitchen Spices
A complete guide to Indonesian kitchen spices — types, functions, how to prepare, and how to store them so your dishes always turn out great.
What Is a Kitchen Spice (Bumbu Dapur)?
Bumbu dapur (kitchen spices/seasonings) is a collection of natural ingredients — roots, rhizomes, seeds, leaves, and even fruits — used to add flavor, aroma, color, and texture to dishes. In Indonesia, kitchen spices aren't just an accompaniment, but the soul of every dish. Rendang, gulai (curry), soto (soup), and sambal (chili paste) — all of them come from the right blend of spices.
What makes Indonesian cuisine unique is the richness and combination of its spices. A single dish can use 5-10 types of spices at once, each contributing a different flavor character — spicy, savory, warm, fresh, or fragrant.
Categories of Kitchen Spices
To make it easier to understand, kitchen spices can be grouped based on their form and function:

Bawang merah (shallot), bawang putih (garlic), jahe (ginger), kunyit (turmeric), lengkuas (galangal), kencur (aromatic ginger). This group forms the base of almost all Indonesian dish seasonings — usually ground first before sautéing.
Ketumbar (coriander), merica (pepper), kemiri (candlenut), jinten (cumin), pala (nutmeg), cengkeh (cloves), kayu manis (cinnamon). Usually toasted first to bring out maximum aroma, then ground or added whole while cooking.
Daun salam (bay leaf), daun jeruk (kaffir lime leaf), daun kemangi (basil leaf), daun kunyit (turmeric leaf), serai (lemongrass). Used whole or sliced, usually added at the start or middle of cooking to release their aroma.
Cabai merah (red chili), cabai rawit (bird's eye chili), cabai hijau (green chili) — provide a spiciness level that can be adjusted to taste.
Base Spice Pastes: Red, White, and Yellow
In Indonesian cooking, you'll often come across the term "bumbu dasar" (base spice paste) — a ground spice blend that forms the foundation of many recipes:
- Red base paste (bumbu dasar merah) — red chili, shallot, garlic, tomato. The base for balado, rendang, and sambal goreng.
- White base paste (bumbu dasar putih) — shallot, garlic, candlenut, a little or no turmeric. The base for opor, soto, and sayur lodeh.
- Yellow base paste (bumbu dasar kuning) — white base paste plus a larger amount of turmeric. The base for curry, gulai, and yellow rice (nasi kuning).
Once you have all three base spice pastes ready in the fridge (they can be made in a batch and frozen), everyday cooking becomes much faster.
How to Prepare Spices Correctly
- Wash thoroughly before use — especially rhizomes, which often have soil clinging to them.
- Toast dry spices (coriander, pepper, cumin) briefly in a dry pan before grinding — the aroma will come out much stronger.
- Sauté the ground spice paste until fully cooked — raw spices can make a dish taste raw and off. Sauté over medium heat until fragrant and the color changes.
- Add aromatic leaves at the right time — bay leaf and lemongrass are usually added early, while kaffir lime leaf is often added later to keep its aroma fresh.
- Crush, don't always grind — galangal and lemongrass are better simply crushed so their aroma comes out without clouding the broth.
How to Store Kitchen Spices
- Fresh rhizomes (ginger, turmeric, galangal, aromatic ginger) — store in a cool, dry place, or in the fridge wrapped in paper/tissue to prevent dampness and spoilage. They can also be sliced and frozen.
- Shallots & garlic — store in a dry, well-ventilated place, not in the fridge, as they can sprout and become soft.
- Dried spices (coriander, pepper, nutmeg) — store in an airtight container, away from direct sunlight, so the aroma doesn't fade.
- Ready-to-use ground spice paste — can be frozen in small containers or ice cube trays, then taken out as needed when cooking.
- Fresh aromatic leaves (kaffir lime leaf, bay leaf) — store in the fridge in a perforated bag, or dry them for longer storage.
Why Is It Important to Know About Kitchen Spices?
- Tastier and more consistent dishes — understanding each spice's function lets you adjust the flavor to your taste.
- More cost-efficient — knowing how to store properly reduces spices going to waste.
- Health benefits — many kitchen spices have natural properties, from anti-inflammatory effects to aiding digestion.
- Preserving culinary heritage — spice blends are part of the Nusantara culinary identity passed down across generations.
