A clear Jakarta restaurant-style oxtail soup with spoon-tender meat, intact potato and carrot, and a restrained perfume of nutmeg, clove, ginger, cinnamon, and pepper.
onion, garlic, ginger, black pepper, nutmeg, clove, cinnamon
A five-minute blanch removes blood and loose protein, then a bare simmer dissolves collagen without emulsifying fat into the broth. Vegetables and nutmeg go in late so each stays distinct.

What belongs where
One dish. Distinct flavour parts.
Sop Buntut is led by clear stock, not a heavy bumbu paste. The aromatics season that stock, while chilli, kecap, lime, rice, and emping stay on the table so the main pot remains clear and balanced.
Bumbu or sambal?A 30-second beginner glossary
Bumbu
The dish's seasoning system: it may be ground, sliced, or left whole, but it is cooked into the food. Bumbu does not automatically mean a jarred paste.
Sambal
A chilli-led preparation with its own salt, acid, aroma, and texture. It can be fresh or cooked and usually remains a condiment, even when you make it during the recipe.
Sauce, glaze, or broth
These words describe function and texture. A broth carries the dish; a glaze coats it; neither becomes bumbu simply because it is strongly seasoned.
Pelengkap
The accompaniments that complete a plate - lalapan, rice, crackers, herbs, lime, or fried shallot. Add them at serving unless the method says otherwise.
01
Broth or stockCooked into the dish
Clear oxtail stock
kaldu buntut bening
Make it
Blanch the oxtail in separate water, rinse it, wash the pot, then begin again with measured fresh water and ginger. Skim early and hold only a bare simmer so fat and loose protein do not emulsify into the liquid.
Ready when
The stock is clear amber with tiny edge bubbles; the meat yields to a skewer but can still be lifted from the pot on its bone.
Keep separate
This is the dish's broth, not sambal and not a blended bumbu. Keep the finished table condiments out of the stockpot.
Store safely
For make-ahead stock, strain into shallow containers, cool and refrigerate within 2 hours, then de-fat while cold. Reheat until piping hot before adding freshly cooked vegetables.
Sweat onion and garlic in butter or oil until sweet, then briefly bloom measured clove, cinnamon, and pepper before they enter the stock. Add nutmeg late and sparingly so it perfumes rather than dominates.
Ready when
The onion is translucent and sweet, garlic has no raw bite, and the spice smells warm rather than medicinal.
Keep separate
This is a seasoning build, but not the thick ground paste many cooks picture when they hear bumbu. It disappears into the broth rather than becoming a side condiment.
Store safely
Once added, store it as part of the finished broth. Do not leave the butter-and-onion mixture at room temperature while the stock cools.
Set out lime, a trusted prepared sambal rawit, kecap manis, rice, and emping in separate bowls. The measured soup recipe does not require you to stir any of them into the communal pot.
Ready when
Each bowl of soup starts clear and beef-forward; diners can add acid, chilli, sweetness, and crunch one small amount at a time.
Keep separate
The listed sambal is an optional table condiment, not a hidden sub-recipe and not part of the soup bumbu. Omit it if you do not have one you trust.
Store safely
Follow the sambal and kecap package directions. Keep cut lime and homemade condiments chilled; discard table portions contaminated by used spoons.
Storage notes are conservative home-kitchen guidance. Chill perishable food within 2 hours, keep it at 5°C or colder, and follow local food-safety and package directions when they are stricter.
Step-by-step method
Cook in order. Follow each cue.
Read the action and cue together. Move on when the food matches the cue.
01
15 min
Blanch and clean the oxtail
Trim only thick exterior fat. Bring 3 L water to a full boil, add oxtail, and boil for 5 minutes. Drain, rinse coagulated scum from the meat with warm water, and wash the pot before the real stock begins.
The drained pieces look clean between the bones and the pot has no grey foam stuck to it.
Common mistake: Skipping the clean pot carries the first blanch's scum into the finished broth.
Recovery: Pause before the next step, compare the cue, then correct heat, moisture, or seasoning while the dish is still flexible.
02
1 hr 30 min
Start a clear bare-simmer stock
Return oxtail with 2.5 L fresh water and bruised ginger. Bring up slowly, then hold at 88–95°C: small bubbles at the edge with only an occasional centre bubble. Skim beige foam and thick fat during the first 15 minutes; partly cover and top up only with boiling water if meat becomes exposed.
Pale clear stock quivers quietly around clean oxtail pieces; there is no rolling turbulence.
Common mistake: Hard boiling emulsifies fat and protein into a cloudy, greasy broth.
Recovery: Lower the heat immediately, skim or stir gently, and continue at a small simmer until the surface calms.
03
12 min
Sauté restrained soup spices
Melt butter over medium-low. Cook onion 7–9 minutes until translucent and lightly gold. Add garlic, cloves, cinnamon, and crushed pepper for 60–90 seconds, just until fragrant, then scrape everything including the butter into the stock.
Sweet onion and warm pepper smell lead; garlic and whole spices are fragrant but not browned.
Common mistake: Dark garlic or extra handfuls of spice make the clear soup bitter or medicinal.
Recovery: Move the pan off heat, scrape only the unburnt paste into a clean spot, add a small splash of oil or liquid, and restart gently.
04
1 hr 15 min
Cook until spoon-tender
Continue the bare simmer, testing after about 2½ hours total cooking. A skewer should enter with little resistance and a spoon should cut the meat, while it still remains attached enough to lift. Timing varies with tail section and animal age.
Gelatin glistens at the joint and meat pulls slightly from bone without collapsing.
Common mistake: Stopping because the timer rang leaves chewy collagen; boiling harder does not make it tender faster.
Recovery: Lower the heat immediately, skim or stir gently, and continue at a small simmer until the surface calms.
05
15 min
Strain, de-fat, and standardise
Lift oxtail carefully. Strain broth through a fine sieve into a clean pot and skim surface fat. Measure and top up with hot water to 1.8 L so seasoning and vegetable timing stay repeatable. For the clearest result, chill overnight and lift off solid fat before continuing.
The measured broth is clear amber with only tiny separate fat droplets.
Common mistake: Seasoning an unknown reduced volume is how a long soup becomes unexpectedly salty.
Recovery: Pause before the next step, compare the cue, then correct heat, moisture, or seasoning while the dish is still flexible.
06
20 min
Cook vegetables in order
Bring the broth to a gentle boil. Add 3 cm potato chunks for 8 minutes, then carrots and oxtail for another 7–10 minutes. Add salt, sugar, optional MSG, and freshly grated nutmeg only when the vegetables are nearly tender. Taste after 2 minutes.
A knife enters potato and carrot centres, but every piece keeps a clean edge; beef remains the dominant aroma.
Common mistake: Adding vegetables with raw oxtail turns them to mush hours before the meat softens.
Recovery: Pause before the next step, compare the cue, then correct heat, moisture, or seasoning while the dish is still flexible.
07
13 min
Finish fresh and serve separately
Add tomato wedges, spring onion, and celery leaves for only 1–2 minutes. Divide oxtail and vegetables, ladle over piping-hot broth, and top with fried shallot. Put rice, lime, sambal rawit, kecap manis, and emping on the table rather than muddying the whole pot.
Clear amber broth frames intact vegetables, bright green herbs, and tender oxtail.
Common mistake: Boiling tomato and herbs until dull removes the fresh contrast that lifts the rich stock.
Recovery: Lower the heat immediately, skim or stir gently, and continue at a small simmer until the surface calms.

9/9
Can I make Sop Buntut in a pressure cooker?
Yes. Blanch first, then pressure-cook oxtail with 2 L water and ginger for 35 minutes at high pressure followed by a 20-minute natural release. Check tenderness and add 8–10 minutes only if needed; sauté spices and cook vegetables afterward on the stovetop.
How do I keep Sop Buntut clear?
Blanch, wash the pot, skim early, and hold a bare simmer. Straining and chilling overnight make de-fatting easier; a rolling boil is the fastest way to cloud it.
What is the best make-ahead point?
Cook and strain the oxtail broth a day ahead, cool it in shallow containers within 2 hours, and refrigerate. Remove the solid fat, then cook fresh potato, carrot, tomato, and herbs when reheating.
What is the decisive ready cue for Sop Buntut?
Build a clear amber broth and know exactly when oxtail is tender but still attached to the bone. Look for clear amber soup, sharp-edged vegetables, bright green herbs: Potato and carrot are tender through the centre; tomato and herbs remain fresh and recognisable.
What should I do if Sop Buntut misses its cue?
Hard boiling emulsifies fat and protein into a cloudy, greasy broth. Lower the heat immediately, skim or stir gently, and continue at a small simmer until the surface calms.
How should I scale Sop Buntut?
Scale the measured ingredients with the serving count, then scale the vessel or work in batches. Keep the same visual finish - clear amber soup, sharp-edged vegetables, bright green herbs - rather than forcing the original timer.
Which substitutions are tested for Sop Buntut?
meaty beef oxtail pieces: meaty beef short ribs or bone-in shank, though the dish is no longer strictly sop buntut; unsalted butter: neutral oil for a dairy-free soup; black peppercorns: white pepper for a paler, gentler broth; fresh nutmeg: 0.25 tsp ground nutmeg
Which Sop Buntut ingredients should not be swapped casually?
meaty beef oxtail pieces: Ask for evenly cut meaty middle sections; thin tail tips give bone without enough meat.; cloves and cinnamon: Do not add extra star anise or cardamom automatically; too much whole spice makes the broth medicinal.; fresh nutmeg: Measure it; more nutmeg does not make a better soup.; lime, sambal, kecap manis, and emping: Check kecap and crackers for soy, wheat, and shared-fryer allergens.
How do I keep the Sop Buntut broth clean?
Hold a gentle simmer and keep noodles and garnish separate until serving. If the surface turns violent, lower the heat before making another adjustment.
