What the AI looks for in Walnut Oils
- Roasted vs. unroasted or refined
- Choose roasted or unrefined oil for flavor and refined oil for cooking with heat. Roasted and unrefined walnut oil is a flavoring oil that turns bitter when heated. Refined walnut oil is milder and tolerates more heat.
- Rancidity risk
- Buy small bottles, refrigerate after opening and use within a few months. Walnut oil is high in polyunsaturated fats, including omega-3, so it oxidizes faster than most cooking oils.
- Packaging
- Prefer tins or dark glass. Light speeds up oxidation of delicate nut oils.
- Use case
- Use it as a finishing oil in vinaigrettes, on salads, over vegetables or in baking. Its flavor is the reason to buy it, and most of that flavor is lost at high temperatures.
Brands that matter
- La Tourangelle: French-style roasted nut oils sold in tins, widely available.
- Huilerie J. Leblanc: Traditional French artisan maker of roasted nut oils.
- Spectrum: Has sold culinary nut oils, including refined options suited to heat.
What to avoid
- Frying or high-heat searing with roasted walnut oil.
- Large bottles you won't finish before the oil turns rancid.
- Storing an opened bottle at room temperature for long periods.
Questions
Should walnut oil be refrigerated?
Yes, after opening. Cold slows rancidity. It may turn cloudy in the fridge, which is harmless and clears at room temperature.
