Hanukkah Prep: Golden Schmaltz and Onion Gribenes
Slow-rendered chicken fat turns clear and golden while the skin and onions become deeply browned, savory little cracklings. Save the schmaltz for holiday cooking and serve the gribenes warm, with just enough salt to bring out their crisp edges and sweet onion flavor.

Golden Chicken Schmaltz
A little water lets the chicken fat begin rendering gently before the skin starts to brown. Adding onion toward the end flavors the fat without burning the onion during the longer rendering stage.
Ingredients
- 2 lb raw chicken skin and attached fat trimmings
- 1/2 cup water
- 1 large yellow onion, cut into thin quarter-moons
Instructions
- Pat the chicken skin and fat dry, then cut into roughly 1/2-inch pieces. Partially freezing slippery skin for 15–20 minutes makes it easier to cut.
- Put the skin, fat, and water in a wide, heavy saucepan or Dutch oven. Bring to a gentle simmer over medium-low heat, then reduce the heat to low.
- Cook uncovered for 40–60 minutes, stirring and scraping the bottom occasionally. The water will evaporate, a pool of clear fat will collect, and the skin will shrink and begin turning pale gold. Keep the heat gentle; the fat should not smoke.
- Add the onion and continue cooking for 15–25 minutes, stirring more frequently as the solids brown. Stop when the skin is crisp and deep golden and the onions are richly browned but not black.
- Set a fine-mesh metal strainer over a dry heatproof bowl. Carefully strain the fat, reserving all the skin and onions for the gribenes component. Let the solids drain without pressing them.
- Allow the schmaltz to cool until warm but still liquid, then transfer to clean, dry, heat-safe jars. Expect roughly 1 1/2–2 1/2 cups, depending on how fatty the trimmings were.
Notes
- Use plain, unseasoned chicken trimmings; heavily marinated or sugary skin can scorch.
- For clean-flavored schmaltz, stop before the onions become nearly black. The fat should smell pleasantly roasted, never acrid.
- No additional cooking fat is needed: the chicken renders in its own fat.
Crisp Gribenes with Browned Onions
Draining the cracklings promptly keeps them from sitting in fat, while salting them warm seasons their irregular, crisp surfaces.
Ingredients
- all rendered chicken-skin cracklings and browned onions reserved from the schmaltz
- to taste fine sea salt
Instructions
- Spread the drained chicken skin and onions in a single layer on a wire rack set over a sheet pan.
- If the skin is still chewy, return the solids to the rendering pot with a spoonful of the freshly rendered schmaltz. Cook over medium-low heat for 3–8 minutes, stirring often, until crisp. Remove any onion pieces that finish browning before the skin.
- Drain again, sprinkle lightly with salt while warm, and let stand for 3–5 minutes. The skin will crisp further as it cools slightly.
- Serve warm rather than piping hot, when the contrast between crunchy skin and sweet browned onion is clearest.
Notes
- Some onion pieces will remain soft and jammy; aim for crisp chicken skin rather than trying to make every onion fragment brittle.
Overall Timing / Workflow
Both components come from one pot, with the separation and final draining done only after the rendering is complete.
Instructions
- 0:00 — Cut the chicken skin and fat and start rendering with the water.
- 0:15 — Slice the onion and set out a strainer, dry heatproof bowl, jars, and draining rack.
- 0:55–1:15 — Once the water has evaporated and the skin is beginning to color, add the onion.
- 1:10–1:40 — Strain when the solids are deeply golden. Finish crisping the gribenes only if necessary, then salt and drain.
- Cool and store the schmaltz while serving the warm gribenes.
Notes
- Timing depends on the proportion of skin to fat and the width of the pot; color, bubbling, and texture are better guides than the clock.
Plating
Keeping the cracklings separate preserves their texture and leaves the schmaltz ready for cooking.
Instructions
- Pile the warm gribenes and browned onions in a shallow serving dish, leaving them loosely arranged rather than compressed.
- Transfer the golden schmaltz to jars for storage; it is a cooking ingredient rather than a sauce to pour over the cracklings.
- If preparing ahead, leave the gribenes uncovered only until cool, then refrigerate rather than sealing them while warm.
Leftover Path
Separate storage protects the fat from moisture and makes the cracklings easier to re-crisp.
Instructions
- Refrigerate both components within 2 hours of cooking. Keep the schmaltz in a sealed container for up to 1 week, or freeze in small portions for up to 3 months. This rendering process does not make it shelf-stable.
- Refrigerate gribenes in a separate airtight container for up to 3 days.
- Re-crisp gribenes on a sheet pan at 350°F for 5–10 minutes, watching the onions carefully so they do not burn.
- Use the schmaltz for roasting potatoes, cooking onions, or frying latkes; scatter leftover gribenes over savory dishes just before serving.
