Sweet, deeply savory, and impossibly rich, this caramelized onion jam is the kind of condiment that makes everything it touches taste more special. The magic here is patience — a slow, steady cook in butter coaxes pounds of sliced yellow onions into something silky and deeply amber, with a flavor that's almost unrecognizable from where it started. A splash of apple cider vinegar and a drizzle of honey balance the natural sweetness with just enough brightness, while fresh thyme ties it all together with an herby, aromatic finish. Every ingredient in this recipe is naturally free from tree nuts of any kind, so there's no need to scrutinize labels or worry about hidden allergens sneaking into your spread. It's wonderful piled onto a cheese board, stirred into a grilled sandwich, or spooned over roasted meat straight from the jar. Store it in the fridge and you'll find yourself reaching for it 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.
