Indonesian food is inextricably linked to my grandmother for me. As soon as you entered her house, the smell of trassi, galangal and homemade sambal greeted you. There were no cookbooks or fixed recipes - only years of experience, cooking by feel and constant tasting. And no blender was involved: with a mortar and pestle she mixed the spices until everything was just right. Those memories still form the core of the Indonesian cuisine for me.

The foundation: The Boemboe

Almost every Indonesian dish starts with a boemboe. This is a freshly ground spice paste that serves as the flavor base. Instead of adding dry spices directly to the liquid, the boemboe is first sautéed (tumis) in oil. This process ensures that the aromas of the fresh ingredients such as shallot, garlic and chiles are released optimally. A boemboe is only ready when the oil starts to separate from the paste.

Regional differences: Java versus Sumatra

Within the archipelago there are distinct flavor profiles to point out. The two best-known currents are:

1- Javanese: This cuisine is known for balance and a preference for sweet. Through the use of Ketjap Manis and Gula Djawa (palm sugar) the dishes are often milder and more syrupy.

2- Sumatran: Here the emphasis is on heat and the use of coconut milk. In regions such as Padang many fresh chiles and turmeric are used, resulting in spicy and aromatic curries without the addition of sweet soy sauces.

Essential flavorings

To achieve the authentic Indonesian flavor, a number of ingredients are indispensable in the pantry:

1-Trassi: Fermented shrimp paste that provides a deep, savory umami flavor.

2- Laos: A rhizome related to ginger, but with a fresher and more resinous flavor.

3- Ketoembar & Djinten: Coriander seed and cumin; the standard duo for a warm, earthy base.

4- Sereh (Lemongrass): Gives a fresh aroma to stews and rice.

5- Djeroek Poeroet: The leaf of the kaffir lime, essential for the characteristic scent of many sauces.

Balance in the pan

The strength of Indonesian cuisine lies in the combination of contrasts: the fattiness of coconut milk against the sourness of tamarind, and the heat of chiles against the sweetness of palm sugar. By mastering these basic techniques and ingredients, the foundation is laid for any authentic dish.

FAQs Making boemboe yourself: the basis of Indonesian cuisine:

1. What exactly is boemboe?

Boemboe is a spice paste that forms the flavor base of many Indonesian dishes. It usually consists of finely ground fresh ingredients such as onion, garlic, ginger and spices, which together provide that typical deep, aromatic flavor.

2. What is the difference between boemboe and a spice mix?

A boemboe is a fresh or wet spice paste, whereas a spice mix usually consists of dried spices. With a boemboe you create a more intense, fuller flavor because the fresh ingredients release their aromas during frying.

3. How long can you store homemade boemboe?

Homemade boemboe can be stored for about 3 to 5 days in a sealed jar in the refrigerator. Want to keep it longer? Then you can freeze the boemboe in portions, for example in an ice cube tray.

4. For which dishes do you use boemboe?

Boemboe is the flavor base for dishes such as rendang, nasi goreng, bami, soto and various curries. You can also use it to give chicken, tofu, vegetables or meat extra depth.

5. Do you have to fry boemboe first?

Yes, it is important to first gently fry the boemboe in oil. This intensifies the flavors and removes the raw taste of, for example, onion and garlic. This process is also called “fruiteren” (sautéing) and is essential for an authentic result.
