The short version
Bacon cooked down with onion, brown sugar, vinegar and usually coffee until it's a dark spreadable paste. It's very rich, faintly sweet, deeply smoky, and it's the single most talked-about thing you can put on a board. Half an ounce a head is plenty.
What it is
Chopped bacon rendered and simmered with caramelised onion, brown sugar or maple, cider vinegar, and often brewed coffee for bitterness. Cooked long enough that the bacon breaks down into a spreadable texture rather than staying in pieces.
- Taste
- smoky, salty, sweet, with a coffee-bitter finish
- Texture
- thick and slightly chunky, spreadable
- Look
- very dark brown, glossy, almost black
The mechanism is stacking all four base tastes at once — salt, sweet, sour and bitter — plus smoke and umami. That density is why a small amount registers so strongly, and why it needs a plain base: on a sharp cheese it works, on a complicated bite it collides.
What it pairs with — and why
| Pair it with | Why it works |
|---|---|
| Aged cheddar | Smoke and salt against sharp acid. The cheddar's bite is the only thing that cuts it. |
| Brie | Rich on rich, which sounds wrong until the vinegar in the jam does the cutting. Very popular. |
| Pretzel crisps and sturdy crackers | It's heavy; it needs a base that won't collapse under it. |
| Aged gouda | Caramel meeting maple and smoke — the flavours line up exactly. |
| Fresh goat cheese | Tang against fat and smoke, and the only pairing here that lightens it. |
| Burgers and eggs | Not a board, but it's why the jar exists. |
Skip it with: anything delicate, anything already smoked, and any board that's also serving smoked almonds and smoked salmon. One smoky thing is a feature.
How to prep it for the board
1. Decant into a small bowl with a spreader. 2. Serve it at room temperature. Cold from the fridge it's solid and greasy. 3. Serve 0.5 oz per person — it's the richest thing on the board. 4. Give it a plain base. Water crackers or pretzel crisps, not something seeded and flavoured. 5. Warm it gently for ten seconds if it's stiff. 6. Say it's not vegetarian. It looks like a jam, and guests assume. 7. Fix: too rich? A squeeze of lemon or a splash of cider vinegar stirred in cuts it noticeably.
What to buy
| Product | Where | Notes |
|---|---|---|
| Small-batch bacon jam | Cheese shops, farmers markets, specialty | Varies enormously by producer. Taste before committing to a board. |
| Stonewall Kitchen bacon onion jam | Grocery, specialty | The most widely available. Reliable and sweet. |
| Maple bourbon bacon jam | Specialty, online | Sweeter and boozier. Good with sharp cheddar. |
| Homemade | Make it | A pound of bacon, two onions, brown sugar, cider vinegar, coffee. About an hour. |
Label check: bacon should be first. Some jars are mostly caramelised onion with bacon flavour, which is a different and cheaper product.
Skip: anything that separates into visible fat in the jar.
