Sweet, tangy, and deeply savory all at once, this caramelized onion jam is the kind of condiment that quietly steals the show on any cheese board, burger, or slice of crusty bread. The magic comes from patience — low, slow heat coaxes the natural sugars out of the onions until they collapse into something rich and almost unrecognizable from their raw state. Honey and apple cider vinegar layer in a gentle sweetness and brightness, while fresh thyme keeps the whole thing grounded and aromatic. Because the recipe relies entirely on butter, onions, and pantry staples, there's nothing hidden to worry about — no eggs lurking in a glaze or binding agent, just clean, honest ingredients doing beautiful work. The technique of adding small splashes of water as needed is a simple but brilliant trick that prevents scorching and keeps the onions cooking evenly all the way through. A spoonful stirred into a pan sauce or spread over a grilled cheese takes the whole dish somewhere special. Make a batch on the weekend and you'll find yourself reaching for the jar all week long.

Melt the butter in a large heavy-bottomed skillet over medium heat until foamy and just beginning to subside.
Add the sliced onions and salt, tossing to coat. Cook over medium heat, stirring every 3–4 minutes, until the onions have fully wilted and turned pale gold, about 20 minutes. If the onions begin to stick or brown unevenly before they have softened, add 1 tbsp of water and scrape up any fond.
