What You’ll Need (Ingredients & Why They Matter)
- Yellow Onions: 4-5 large (about 6-7 cups / 1.5 kg sliced) — The essential base for our rich Mahogany Caramelized Spread, providing abundant natural sweetness as they slowly cook down. For a deeper flavor, I sometimes swap in red onions for half the yellow.
- Olive Oil: 2 tablespoons (30ml) — Used for sautéing the onions, contributing a smooth texture and fruity note.
- Butter: 1 tablespoon (14g) — Adds richness and helps achieve that deep caramelization. (For a dairy-free onion jam, use all olive oil — I often do this for dietary swaps!)
- Brown Sugar: 1/4 cup (50g) packed — Enhances the onions’ natural sugars and deepens the “mahogany” color, essential for this unique onion jam recipe.
- Balsamic Vinegar: 1/4 cup (60ml) — Provides a crucial tangy counterpoint and complexity, a signature of truly great onion jam. Opt for a good quality balsamic for superior depth; it truly makes a difference.
- Ruby Currants (dried): 1/4 cup (40g) — A delightful pop of tartness and beautiful ruby color, adding a gourmet touch. (Dried cranberries or cherries also work wonderfully if currants are hard to find.)
- Fresh Thyme: 1 teaspoon (or 1/2 teaspoon dried) — A classic herb pairing that complements the sweet and savory notes.
- Salt: 1/2 teaspoon — Essential for balancing and enhancing all the flavors.
- Black Pepper: 1/4 teaspoon — Adds a subtle warmth and spice.
- Optional flavor boosters: A pinch of chili flakes for a subtle kick, or a bay leaf during cooking for aromatic depth.
How to Make Mahogany Caramelized Spread with Ruby Currants Step by Step
Crafting this incredible onion jam is simpler than you might think, mainly requiring patience for the magic of caramelization to unfold.
- Prep the onions: Thinly slice 4-5 large yellow onions (about 6-7 cups / 1.5 kg sliced). Aim for uniform slices; this is key for even cooking and consistent texture in your spread.
- Caramelize slowly: In my trusty 10-inch heavy-bottomed pot or Dutch oven, heat 2 tablespoons olive oil and 1 tablespoon butter over medium-low heat until shimmering. Add all the sliced onions, stir well to coat, and cook slowly for 30-45 minutes, stirring occasionally, until they are deeply golden brown and beautifully softened. You’ll notice a sweet aroma filling your kitchen as they transform. If they start to stick, add a splash of water or broth to loosen the fond. This slow process builds the profound “mahogany” flavor for your onion jam.
- Build the flavor: Stir in 1/4 cup packed brown sugar, 1/4 cup balsamic vinegar, 1/4 cup dried ruby currants, 1 teaspoon fresh thyme (or 1/2 teaspoon dried), 1/2 teaspoon salt, and 1/4 teaspoon black pepper. The mixture will look glossy and vibrant.
- Simmer to perfection: Bring the mixture to a gentle simmer, then reduce the heat to low. Cook for another 15-20 minutes, stirring occasionally, until the liquid has mostly evaporated and the onion jam is thick and glossy. It should mound on a spoon and glisten like jewels, indicating it’s ready.
- Cool & Store: Remove the finished onion jam from heat. Let it cool completely — this allows the flavors to deepen and the spread to thicken further. Transfer to clean, airtight jars. Store your homemade Mahogany Caramelized Spread with Ruby Currants in the refrigerator for up to 2-3 weeks, making it a fantastic meal prep recipe for busy families.
