Biltong Seasoning: What Goes In, and Why Coriander Runs It
Published UpdatedBiltong seasoning is toasted coriander, coarse salt, black pepper and vinegar, and each one has a job. Coriander is the signature, salt pulls water out, pepper adds bite, and vinegar isn't a spice at all: it's the acid doing the preserving.
Get the coriander right and everything else is adjustment. Get it wrong and no amount of salt, pepper or patience will make the result taste like biltong. That's the whole argument, so here's why.
Coriander Is the Signature, Not an Option
Coriander seed is what makes biltong taste like biltong. Toasted and cracked, it's warm, faintly citrusy and slightly sweet, and it sits on top of the beef rather than fighting it. Take it out and you've got salted dried beef, which is a fine thing and not biltong.
The history backs that up. Coriander came into South African curing on the spice trade and never left, which is why every traditional recipe starts from the same seed. If a mix calls itself biltong seasoning and coriander isn't near the top of the list, it's named after something it isn't.
Salt, Pepper, Fennel: What Each One Does
| Ingredient | Job | Notes |
|---|---|---|
| Coriander seed | Signature flavor | Toast, then crack coarsely. Never powder. |
| Coarse salt | Draws out water, preserves, seasons | Coarse, so it dissolves slowly and doesn't over-salt the surface. |
| Black pepper | Heat and bite | Coarse-cracked. Fine pepper turns dusty on a dry surface. |
| Fennel seed | Sweet aniseed lift | Not universal. Plays directly off the coriander. |
| Brown or cider vinegar | Acidifies the surface, preserves, tenderizes | The wet step, applied before the dry spice. |
Fennel is the one that divides people. In the Cape winelands recipes I grew up on it was always there: faintly sweet, aniseed-forward, and against the citrus edge of coriander it lifts the whole thing instead of adding a flavor you can name. Heavy-handed, it takes over; used lightly, you'd only notice if it were missing.
Vinegar Does the Work Nobody Credits
Vinegar is why biltong can be air-dried without ever being cooked. The beef is dipped or wiped in brown or cider vinegar before spicing, and the acid drops the surface pH, which holds spoilage organisms back during the days the meat hangs wet and vulnerable. It also softens the surface a little and carries the salt in.
Traditionally that's brown spirit vinegar. Cider vinegar works and leaves a faint fruitiness; malt vinegar is assertive; white vinegar is sharp and flat. The choice changes the finish more than you'd expect. Whichever you use, it goes on before the spice so the dry mix has something to grip.
Regional and Modern Variations
The base is stable. The variations are where brands differentiate:
- Chili and peri-peri. The most common variation and the oldest. Dried chili flake or a peri-peri blend over the standard base. Hill Country Heat is our version.
- Garlic. Usually granulated rather than fresh, because fresh garlic adds moisture exactly where you don't want it.
- BBQ. An Americanized profile, almost always sweetened, and usually further from biltong than the label lets on.
- Worcestershire. An old addition on the wet side, mixed into the vinegar.
Sugar in a biltong spice packet is a warning sign. Traditional biltong isn't sweet, and sugar in the mix is usually doing one of two things: standing in for depth the blend doesn't have, or setting up a jerky flavor under a biltong name. Check the panel for sugar, dextrose and maltodextrin before you buy. Ours reads beef, salt, pepper, coriander, Worcestershire sauce and white vinegar — no MSG, no artificial additives; full ingredients and nutrition panel on the bag.
Best biltong spice: what to look for in a ready-made mix
The best biltong spice is a ready-made mix that lists coriander first or second, uses coarse rather than powdered seed, contains no sugar, dextrose or maltodextrin, and keeps fillers like rusk flour and anti-caking agents off the panel. Salt should be in the mix but shouldn't lead it, and the vinegar step is yours to do at home, not something the packet can supply.
A few quick tells once the bag's open:
- Look at the grind. You should see split husks and cracked halves. A uniform beige powder means the top note's already gone.
- Smell it. Warm and citrusy is right. Dusty or flat means old seed or too much salt.
- Read the order. Ingredients are listed by weight. Coriander first means you bought spice; salt first means you bought salt with a coriander garnish.
- Watch the things you can't pronounce. MSG, hydrolyzed vegetable protein and silicon dioxide aren't dangerous, but you're paying spice prices for them.
How to Toast and Crack Coriander Properly
This is the step that separates good home biltong from disappointing home biltong, and it takes four minutes.
- Dry pan, medium heat. No oil. Coriander seed in a single layer.
- Keep it moving for two to four minutes, until it smells warm and citrusy and a few seeds pop. The color barely changes. Smell's the signal, not sight.
- Cool it completely before cracking. Warm seed crushes to paste.
- Crack coarsely. Pestle and mortar, the flat of a knife, a rolling pin, or a grinder pulsed two or three times. You want split husks and cracked halves, not powder.
Grinding coriander to powder is the standard mistake. Powder coats the beef in a layer that tastes dusty and bitter, and it burns off the top note you toasted the seed for in the first place. Some traditionalists winnow the husks away after cracking; it's optional and it does make a cleaner finish.
A Working Ratio for a Home Batch
Treat this as a starting point per 2 lb (about 1 kg) of trimmed beef, then adjust once you've tasted a batch:
- Vinegar: about 1/2 cup brown or cider vinegar, for dipping or wiping. Excess drains off.
- Coarse salt: 2 tablespoons. Adjust this one first; fine salt at the same volume will over-salt badly.
- Toasted cracked coriander: 2 tablespoons. More is a legitimate choice; less is a mistake.
- Coarse black pepper: 1 tablespoon.
- Fennel seed, cracked: 1 teaspoon.
- Chili flake: 1 to 2 teaspoons, if you want heat.
Vinegar first, spice second, then rest the meat spiced and covered in the fridge for a few hours before hanging. The full method, cure time and hanging included, is in the traditional biltong recipe, and the cut matters as much as the spice: see the best cut of beef for biltong.
What Is Actually in a Commercial Biltong Spice Packet
Pre-mixed biltong spice is convenient and mostly fine, but read the back. Commercial packets often carry MSG or hydrolyzed vegetable protein for savoriness, anti-caking agents like silicon dioxide to keep the blend free-flowing, and sometimes sugar and rusk flour as bulk.
None of that's dangerous. It does mean you're buying salt, filler and flow agent at spice prices, and that the coriander proportion is whatever the blender decided rather than what you'd choose. If the ingredient list opens with salt rather than coriander, you've mostly bought salt.
FAQ
What is biltong seasoning made of?
Traditional biltong seasoning is coriander seed, coarse salt and black pepper, applied to beef that has first been wiped or dipped in brown or cider vinegar. Fennel, chili, garlic and Worcestershire sauce are common additions. Coriander is the defining flavor and is present in every traditional version.
Why is coriander used in biltong?
Coriander gives biltong its characteristic warm, citrusy flavor and is the ingredient that distinguishes it from other dried beef. It entered South African curing through the spice trade and became standard. Toasted and coarsely cracked, it sits alongside the beef flavor rather than covering it.
Do you have to toast coriander for biltong?
Toasting is not strictly required, but it changes the result substantially. A dry pan over medium heat for two to four minutes releases the citrus and warmth in the seed. Untoasted coriander tastes flat and slightly soapy by comparison, and grinding it to powder makes that worse.
Can you make biltong without vinegar?
Vinegar is strongly recommended because it does the preserving work, not the flavoring. The acid lowers surface pH during the days the meat hangs wet, which suppresses spoilage. Skipping it removes a safety step from a process that never applies heat, so it is not a sensible ingredient to omit.
Should biltong seasoning contain sugar?
Traditional biltong seasoning contains no sugar. Sugar in a biltong spice blend usually signals a jerky-style flavor profile under a biltong name, or a blend compensating for a weak spice base. Check the panel for sugar, dextrose and maltodextrin before buying a pre-mixed packet.
