The locals in my area in West Java, mainly prepare boiled rice (nasi) and then keep it on the ready in a Magicom (which is similar to a rice cooker) in their houses for the whole day.
Leftover rice is usually left in the Magicom overnight with added water, and ate as rice porridge (bubur) the next morning, with added thin chicken flakes (bubur ayam).
A favoured way to eat rice here, is by frying it (nasi goreng) and is another alternative for next-day-rice.
It is cheaper & faster for most people here to buy additions to the rice at a nearby stall (warung), than making those additions themselves.
The people here say that:
- "If rice was not part of the meal, you haven't eaten yet", and
- "A meal without rice, is like a sky without stars".
Additions to rice that are favoured here, are:
- Tahu (called Tofu in other areas, as mentioned above by Fred).
- Tempe (also mentioned above by Fred, with a beautiful picture).
- Lalab (vegetable salad).
- Chicken or Fish (fried, steamed, or boiled).
- Bala-bala (also called "Sundanese Pizza", though it is nothing like "Pizza" per sé, but rather some chopped up vegetables (like carrot, cabbage, and sometimes corn), fried with a coating made of flour.
- Saté (long thin sticks, with small pieces of vegetables & chicken-, goat-, or rabbit meat on, grilled over a fire).
- Pisang goreng (fried banana).
Two popular meals that locals also buy at warungs here, are:
- Gehu (abbreviated from: tauge tahu), which is tahu stuffed with spicy bean sprouts (and sometimes also with cabbage, carrots and vermicelli), fried with a coating made of flour.
- Batagor (abbreviated from: bakso tahu goreng), which is minced fish meat, filled into wonton skin as a batagor dumpling, fried in oil, and usually served with a peanut sauce.
Ingredients are most often bought in the market (pasar), though there are a few "foreigner malls" in Bandung where you can also buy the ingredients (and pay MUCH more for it than in the market, unless the seller in the market overcharges you based on the fact that you are a foreigner coming from a country with a much stronger financial currency, but in which case the food should still be very cheap for you).
Locals in most countries don't have a "tongue" for foreign food as much as for their own food, though there are certainly exceptions (and more so amoung people who have travelled).
I have found that a simple thing like "French Toast" is loved incredibly much by the locals here, and they all make it now from time to time. Bread, is not consumed very often here though, and therefore seldom bought. They jokingly say things like:
"If you [an Indonesian] want to learn to speak English faster, you should eat more bread!" (because "English speaking people" are spoken of here, as people who LOVE bread and eat LOTS of it).
