Salo is cured pork fatback, a staple across Eastern European and Slavic cuisines. Making it at home requires just a few ingredients and some patience: you coat thick slabs of skin-on pork fatback in salt and seasonings, then let them cure in the refrigerator for several days. The result is rich, silky, and deeply savory, ready to slice paper-thin and eat on dark bread with garlic.
Choosing the Right Cut
You need pork back fat with the skin still attached. This is sometimes sold as “fatback” at butcher shops or Eastern European delis. Look for pieces that are 1.5 to 2 inches thick, with firm white fat and clean, intact skin. Avoid pieces that are mostly lean meat. Some fat with thin streaks of pink running through it is fine and adds flavor, but the bulk should be pure white fat.
If you can’t find fatback at a regular grocery store, ask a butcher to cut it from a whole hog or check specialty markets. Pork belly can work in a pinch, though it has more meat and less of the traditional texture.
Cleaning and Preparing the Fat
Before curing, scrub the skin side thoroughly. Rub the skin with coarse salt and scrape it with a knife to remove any residue, then rinse under cold water. Pat the entire piece completely dry with paper towels. If your piece is very large, cut it into manageable blocks, roughly 4 to 6 inches long. This makes them easier to handle and ensures the salt penetrates evenly.
The Dry Cure Method
Dry curing is the most common approach and the simplest. For every 2 pounds of fatback, mix about 30 grams (roughly 2 tablespoons) of kosher salt with your chosen seasonings. Many recipes also include a half teaspoon of curing salt (sodium nitrite, also called pink salt or Prague powder), which helps prevent the growth of harmful bacteria, particularly the kind that causes botulism. Sodium nitrite is especially useful when curing at home because it provides a safety margin that regular salt alone doesn’t offer.
Wearing gloves, rub the salt mixture firmly into every surface of the fat, including the skin and any crevices. Get it into the corners and edges. Place the salted pieces into a resealable bag or vacuum-seal them. Set them in the refrigerator and let them cure for 5 days, flipping the bag once a day so the liquid that draws out redistributes evenly across the surface.
The Wet Brine Method
If you prefer a milder, more evenly seasoned result, you can brine the fat instead. Dissolve 4 to 8 tablespoons of salt in 2 cups of water for every pound of fatback. The higher end of that range produces a saltier, more preserved result. You can add garlic cloves, bay leaves, or peppercorns directly to the brine.
Submerge the fatback in the brine, making sure it stays fully covered. A small plate or weight on top keeps it from floating. Refrigerate for 4 to 7 days. The longer it sits, the saltier and firmer it becomes. After brining, remove the salo, rinse it briefly under cold water, and pat it dry.
Seasoning and Spice Rubs
Traditional salo seasoning varies across Slavic cultures, but the most common additions are garlic, black pepper, and paprika. A classic Ukrainian approach is to press thin slices of raw garlic into slits cut across the fat before or after curing. Freshly cracked black pepper is nearly universal.
Eastern Slavic traditions tend toward paprika and garlic rubs, while Western Slavic and Central European versions are more often smoked after curing. You can apply a thick spice rub after the initial salt cure has finished: wipe the surface dry, then press your seasoning blend firmly onto all sides. Bay leaf, coriander seed, and dried dill are other common choices. Let the seasoned salo sit for another day or two in the fridge so the flavors absorb before eating.
A Note on Curing Salt
You’ll see some traditional recipes that skip sodium nitrite entirely, relying on regular salt alone. This works when the fat is very fresh, the cure is heavily salted, and it stays refrigerated throughout. But sodium nitrite exists in curing for a good reason: it suppresses the growth of dangerous bacteria, particularly Clostridium botulinum, the organism responsible for botulism. Only a small amount is needed. If you’re new to curing meat at home, including it is the safer choice. Curing salt is dyed pink so you don’t confuse it with table salt, and it’s widely available online or at butcher supply shops.
Storage
Once cured, salo keeps well in the refrigerator for several weeks, wrapped tightly in parchment paper or plastic wrap. For longer storage, cut it into portions and freeze them. Frozen salo stays good for months and actually slices more easily when partially frozen, letting you shave off paper-thin pieces with a sharp knife.
Keep cured salo cold at all times. It’s a preserved product, but it’s not cooked, so room temperature storage invites spoilage. If it develops off smells, discoloration, or a slimy texture, discard it.
How to Serve Salo
The classic way to eat salo is sliced very thin and laid on dark rye or black bread with raw garlic. In Ukraine, it’s traditionally served alongside ripe tomatoes, sliced onions, and a clove of garlic you bite into between pieces of bread. It’s also a common companion to borscht, often set on the table with green onions and crusty bread so everyone can help themselves.
Other popular pairings include hard-boiled eggs with raw onion and dark bread, fried potatoes with a cucumber and tomato salad, or simply salo with a dab of hot mustard. Some people render small cubes of salo in a pan and use the crispy bits (called shkvarky) as a topping for potatoes, pierogies, or buckwheat. Salo is best enjoyed cold or at cool room temperature, where the fat has a smooth, almost buttery texture that melts on the tongue.
