Pine Nuts

Pine nuts contain high oil content and go rancid quickly at room temperature. Store in an airtight container in the refrigerator or freezer. They are expensive, so proper storage prevents waste.

Toast lightly in a dry skillet over medium heat (2–3 minutes) to enhance their buttery flavor—watch closely as they burn easily.

Add to the end of cooking or as a garnish to preserve their delicate texture.

Buy in smaller quantities since they spoil faster than other nuts.

Smell before use; rancid pine nuts have a musty, off odor and should be discarded.

Basil (classic in pesto)

Garlic

Lemon

Parmesan cheese

Dark leafy greens

Dried fruit (raisins, currants)

Rice and grain dishes

Storing at room temperature too long, leading to rancidity.

Over-toasting, which makes them bitter and burnt.

Adding to hot dishes raw without toasting, missing the flavor boost.
