Lontong Rice Cakes: Indonesian Compressed Rice Recipe

Lontong is an Indonesian rice cake made by cooking rice in a tight wrap until it becomes a firm, sliceable cylinder. Banana leaves add a gentle fragrance, and the plain, compact cakes are especially good alongside saucy dishes; wrapping and cooking methods vary from region to region and household to household.

Ingredients

2 cups (370 g) medium-grain white rice
8 banana-leaf pieces, each about 12 by 14 inches (30 by 35 cm), for wrapping
4 lengths cotton kitchen twine, about 18 inches (45 cm) each
5 quarts (4.7 L) water for simmering, plus more hot water as needed to keep the bundles covered
½ teaspoon fine salt (3 g), optional

Instructions

Rinse and soak the rice. Put the rice in a bowl and rinse it in several changes of cool water, rubbing the grains gently, until the water is mostly clear. Cover with fresh water and soak for 30 minutes. The soak helps the grains cook evenly inside the tightly wrapped cakes. Drain very thoroughly; water left clinging to the rice can make the filling too wet.
Prepare the leaves. Wipe both sides of each banana-leaf piece clean. If the leaves are stiff or crack when bent, soften them briefly over a low gas flame, moving them constantly, or dip them in hot water for 1 to 2 minutes. They should become flexible without browning. Pat dry. Lay two pieces together with their shiny sides facing out, overlapping the long edges slightly, to make four double-layered wrappers. If your leaves are especially large, cut them to the stated size.
Form the cylinders. Roll one double-layered wrapper into a tube about 2 inches (5 cm) wide and 7 inches (18 cm) long. Fold one end closed and secure it firmly with kitchen twine. Stand the tube open-end-up in a cup or small bowl so it is easier to fill. Repeat with the remaining wrappers. A snug roll and secure end matter: loose seams can let rice escape as it expands.
Fill and seal. Divide the drained rice evenly among the four tubes, adding about ½ cup (90 g) to each. The uncooked rice should fill only about one-third of each tube, leaving room for it to swell and bind together. Add the optional salt evenly if you want lightly seasoned cakes. Fold the open end closed, leaving a little space for expansion, then tie it securely. Check each seam and end for gaps.
Simmer until the rice is compact. Arrange the bundles horizontally in a large, heavy pot and pour in the measured water. Add more if needed so they are covered by at least 1 inch (2.5 cm). Set a heatproof plate on top to keep them submerged, without pressing hard, and bring the water to a boil over medium-high heat, about 15 minutes. Reduce the heat to maintain a steady, gentle simmer and cook for 3 hours. Check the pot about every 30 minutes; if the water level drops, add boiling water so the bundles remain covered. Avoid a vigorous boil, which can loosen the wraps or damage the leaves.
Drain and cool. Lift the bundles out with tongs and let excess water drain. Set them on a rack, spaced apart, and leave the wrappers on while they cool for 90 minutes. Refrigerate them after that cooling period and chill for 30 minutes to help the cakes firm up for slicing. Keep the total time at room temperature under 2 hours. The finished cakes should feel firm; when cut, the rice should hold together without a chalky, hard center. If a test cake is still undercooked in the center, rewrap it securely and simmer the remaining bundles for another 30 to 45 minutes.
Slice to serve. Unwrap a fully cooled cake and cut it crosswise into rounds about ½ inch (1.25 cm) thick, or split it lengthwise and cut into bite-size pieces. A slightly damp, sharp knife helps make clean slices. Keep the other cakes wrapped until you are ready to use them.

Tips

Choose the right rice. Medium-grain white rice gives the cakes a pleasantly cohesive texture. Jasmine rice is a practical substitute and brings a floral aroma, though the cakes may be a little less sticky. Long-grain rice can work but may slice less neatly; brown rice needs different cooking conditions and is not a direct swap here.
Make the leaves pliable before rolling. Banana leaves are sold frozen in many Asian grocery stores. Thaw them fully in the refrigerator, then warm them gently before shaping. If a piece splits, patch it with an overlapping piece rather than relying on a single thin layer.
Do not overfill the wrappers. Rice expands considerably as it cooks. Filling a tube more than one-third full leaves too little room and can force open the ends. Tie the closures securely, but do not crush the tube into a flat shape.
Keep the simmer gentle and the water high. A low, steady simmer gives the rice time to hydrate and compact evenly. Check the pot regularly, and use hot water for topping up so the cooking temperature does not fall sharply.

Serving Suggestions

Lontong is usually served as a mild, filling base rather than as a strongly seasoned dish on its own. Pair slices with sayur lodeh, a coconut-milk vegetable stew, or with gado-gado, Indonesian vegetables dressed with peanut sauce. It also fits well in lontong sayur, where pieces are served in a spiced vegetable and coconut broth, and with satay, where its clean rice flavor balances grilled meat and savory sauce.

For a simple meal, arrange the slices in a shallow bowl, spoon hot sauce or broth over them, and add vegetables, fried shallots, or a little sambal at the table. Keep the rice cakes separate until serving if you want their edges to stay distinct; for a softer, more stew-like bowl, let them sit in the broth for a few minutes. Because lontong is mild, taste the accompanying sauce before adding extra salt to the rice.

Variations

Use a different wrapper. Banana leaves are traditional and contribute a subtle aroma, but they can be difficult to find. A purpose-made, food-safe lontong mold is a useful alternative; follow its filling and cooking directions, since designs differ. For a home substitute, cook the rice fully on the stovetop, press it firmly into a small parchment-lined loaf pan, cover, chill until solid, and slice. This is convenient, but it will not have quite the same texture or leaf fragrance as rice cooked in a cylinder.

Adjust the seasoning. Plain lontong is versatile and commonly served without added seasoning. A small amount of salt, as listed, gives the cakes a little flavor on their own. You can omit it when serving them with a salty or strongly seasoned sauce. Avoid adding oily or chunky seasonings to the rice inside the wrappers, because they can interfere with the grains binding into a smooth cake.

Change the shape, not the filling level. If you have shorter or narrower leaves, make smaller cylinders and divide the rice among them, keeping each one no more than one-third full. Smaller cakes may cook sooner, so check one after about 2½ hours and continue simmering if its center is still firm or chalky. The finished texture should be compact rather than mushy.

Storage and Reheating

Rice should not sit at room temperature for long. After cooking, drain the bundles and cool them promptly; refrigerate within 2 hours of cooking, including the cooling time. Once cool, keep the cakes wrapped or place them in an airtight container. They keep for 3 to 4 days in the refrigerator. For longer storage, freeze them individually wrapped for up to 2 months; thaw in the refrigerator before reheating. Freezing can make the texture slightly softer.

To reheat, steam the wrapped cakes for about 10 to 15 minutes, until hot throughout, or microwave unwrapped slices covered with a damp paper towel in short bursts. If reheating a whole cake or a substantial portion as leftovers, heat it to 165°F (74°C), checking the center with a food thermometer. Avoid repeatedly warming and cooling the same cake. Slice only what you plan to serve, and return the rest to the refrigerator promptly.

Frequently Asked Questions

Can I make lontong without banana leaves?

Yes, but the result depends on the substitute. A purpose-made food-safe lontong mold is the closest option, though you should follow its instructions. Without one, cook the rice fully, press it firmly into a lined pan, and chill it before slicing. That produces convenient compressed rice, but it is not quite the same as rice cooked and scented inside banana leaves.

Why did my lontong fall apart when I sliced it?

It may have been underfilled in the sense that the rice did not swell and press together, or it may have been cut while warm. Check that the rice filled roughly one-third of the tube before cooking, the bundles stayed submerged for the full simmer, and the cakes cooled and chilled before slicing. A sharp, slightly damp knife also helps keep the edges neat.

Can I skip soaking the rice?

Soaking for 30 minutes helps the grains hydrate evenly during the long simmer, so it is recommended. If you skip it, the center may take longer to soften and the cakes may cook less evenly. If time is short, you can soak the rice in warm—not hot—water for about 15 minutes, drain it well, and still check a cake for a fully tender center.

How can I tell when the rice cakes are done?

Use the recipe’s 3-hour simmer as a starting point, then check a cooled cake if you are uncertain. The center should be tender, with no separate hard or chalky grains, and the slices should hold together. If the center is not ready, tie the wrapper closed again and continue simmering for 30 to 45 minutes, keeping the bundles covered with water.

Can I prepare lontong a day ahead?

Yes. Cook and cool the cakes, then refrigerate them in their wrappers or in a covered container. They will firm up overnight and are often easier to slice the next day. Reheat only the amount you need, and keep the remaining cakes refrigerated rather than leaving them out during serving.
