You can cure pork with salt alone, and people do, but it gives you a different product with a shorter safe life and a greyish colour rather than the bacon most people are picturing. And the shop-bought bacon labelled nitrite-free or uncured is usually not what the label implies either: most of it is cured with celery powder or celery juice, which is a naturally occurring source of nitrate. So the honest answer is that nitrite-free bacon at home is possible, rarer than the internet suggests, and not the same thing as the bacon in the packet you were comparing it to.
We use a traditional cure in our kit, we say so on the pack, and this article explains why, what the alternatives actually are, and how to decide for yourself.
What is in a traditional bacon cure?
A dry cure is a measured mix of salt and sugar with sodium nitrite (E250) and sodium nitrate. The salt draws moisture out of the pork over several days. The sugar balances it and helps the bacon colour in the pan. The nitrite and nitrate protect the meat through the days it spends curing in the fridge, and they are also responsible for the pink colour and the particular savoury flavour that reads as bacon rather than as salted pork.
That is what comes pre-measured in our bacon making kit. You rub it into pork belly, refrigerate it for the time in the booklet, rinse, pat dry, air dry it hanging in the fridge, then slice and fry. No weighing, no guesswork about quantities, which matters because the cure is the preservation rather than the seasoning.
Why did we choose a cure with nitrites?
Reliability in a domestic kitchen. In an ideal world we would leave them out, but this is the easiest and safest way to cure bacon at home: the nitrites are what protect the meat while it cures, across roughly a week in an ordinary fridge that gets opened twenty times a day.
A kit has to work for someone doing this for the first time, with a fridge we have never seen, a piece of belly we have not inspected, and no way for us to check on it halfway through. A measured traditional cure is the method with the longest track record and the fewest ways to get it wrong, so that is the method we send out.
We are not going to make a health argument in either direction here, because that is not ours to make. What we can tell you is what is in the pack and why the recipe is built the way it is. Every ingredient is listed on the pack, and if you have an allergy question, email hello@sandyleaffarm.com before ordering.
What does nitrite-free bacon actually mean in the shops?
Usually it means celery. Celery is naturally high in nitrate, and celery powder or concentrated celery juice is widely used as the curing agent in products sold as uncured or nitrite-free. The chemistry the meat experiences is closer to a traditional cure than the marketing suggests, and you will often see it declared somewhere on the back of the pack.
There is a second category: genuinely salt-only cured pork, sold as such. It exists, it has a long history, and it is a real thing to eat. It is also a different product. Expect a greyer, more muted colour, a saltier and less recognisably bacony flavour, and a shorter window in which it is at its best.
Neither is a con. It is just worth knowing which one you are buying, and which one you would be making.
Can you make salt-only bacon at home?
You can cure pork with salt and sugar alone. If you go that way, recognise what you are taking on: you are relying entirely on salt, cold and drying to keep the meat in good order, and you have removed the ingredient that was covering you through the slow middle days of the cure. That means being stricter, not more relaxed, about everything else.
- Genuinely fresh pork, bought to cure that day, from a butcher you trust.
- Refrigerated throughout, with no stage left out on the worktop.
- A shorter life at the other end. Treat it as something to eat sooner rather than a joint that will sit in the fridge for a fortnight.
- Cooked through, always. That rule does not change with any cure, or without one.
Our kit's recipes are written around the cure we supply, so this is not a swap you can make inside the booklet's timings. It is a separate project, with its own recipe, and we would rather say so plainly than pretend the two are interchangeable.
What if you just do not want to cure at all?
Then make something that never needed a cure in the first place. Our jerky and biltong kits use no cure at all, just seasoning blends and, for biltong, cider vinegar. What preserves those is thorough drying, salt and, in the biltong, the vinegar in the marinade. You buy lean beef, slice it thin, season it and dry it, and there is no nitrite anywhere in the process.
It is the same instinct, satisfied a different way: meat you made yourself, from an ingredient list you can read in one breath. If nitrites are the sticking point, dried beef is the easier place to start than trying to rewrite a bacon cure.
Nitrites and bacon curing FAQs
Does the Sandy Leaf Farm bacon cure contain nitrites?
Yes. It is a traditional dry mix of salt and sugar with sodium nitrite (E250) and sodium nitrate, supplied pre-measured. The nitrites are what protect the meat while it cures.
Is shop-bought uncured bacon really nitrite-free?
Usually not in the way the name suggests. Most bacon sold as uncured or nitrite-free is cured using celery powder or celery juice, which is a natural source of nitrate. Check the ingredients on the back of the pack.
Can I cure bacon with only salt and sugar?
You can, but it is a different product: greyer in colour, different in flavour and shorter lived. It needs very fresh pork, constant refrigeration and eating sooner, and it is not a straight swap inside our kit's recipes.
Which of your kits contain no cure?
The jerky and biltong kits. They use seasoning blends only, with cider vinegar in the biltong marinade, and rely on drying rather than curing salts.
Do I still have to cook home-cured bacon?
Yes, always cook it through before eating, whichever cure you use. Home curing produces raw bacon for the pan, not a ready-to-eat product.
