Peanut Free Caramelized Onion Jam
Sweet, deeply savory, and impossibly rich, this caramelized onion jam is the kind of condiment that makes everything it touches taste more special. Patience is the secret ingredient here — a long, slow cook in butter coaxes the onions from sharp and pungent to meltingly soft and amber-colored, with a natural sweetness that no shortcut can replicate. A hit of honey deepens that sweetness, while apple cider vinegar cuts right through it, and fresh thyme ties the whole thing together with a subtle herbal note. The result is thick, glossy, and jammy in the best possible way — exactly what you want spooned over a cheese board, tucked into a grilled sandwich, or piled onto a burger. Every ingredient in this recipe is straightforwardly whole and easy to source, so there's no need to scrutinize labels for hidden additives or worry about cross-contact from processed products. Keep a jar in the fridge and you'll find yourself reaching for it constantly.

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.
