Walnut Oil
A nutty, roasted flavor, without the mild bitterness of whole walnuts.

Nutrition Perks
Many Americans don't eat enough omega-3 fat, which helps ensure normal brain function, reduces artery-damaging inflammation, and may reduce the risk of dementia, cancer, and heart disease. Walnuts are one of the richest nut sources of omega-3s. In a Penn State study, subjects showed a better physical response to stress, with lower blood pressure, when they ate walnut oil and whole walnuts.

Kitchen Prep
To whip up an easy vinaigrette, Peltre mixes together 1 Tbsp. sherry vinegar, ½ tsp. ground coriander or cumin, and a pinch of salt and pepper. Then she whisks in 2 Tbsp. walnut oil and 1 Tbsp. olive oil until emulsified.
