Native to the Mississippi River Valley, **pecans (*Carya illinoinensis*)** develop their signature buttery snap during a slow 2-year growing cycle. Their thin shells and high monounsaturated-fat content give desserts that “melt-in-the-mouth” quality—yet they shine equally in savoury dishes and salads.
- **Oleic acid** (the same MUFA in olive oil) supports healthy HDL-to-LDL ratios.
- Highest **antioxidant capacity** among nuts—mostly ellagic & proanthocyanidins.
- **Manganese & copper** help collagen formation and blood-sugar regulation.
- Naturally free of gluten and dairy; terrific for keto & paleo snacks.
Drawbacks & Cautions
- **Energy dense**: a casual palmful is ~200 kcal—pre-portion if you track calories.
- Common **tree-nut allergen**—cross-contact possible in mixed facilities.
- High fat oxidises; store cold & dark to prevent rancidity (tastes like crayons).
How to Use Pecans
- Toast 8 min @ 175 °C for deeper flavour; cool before chopping.
- Blend with dates & cacao for a **no-bake brownie crust**.
- Swap into **basil-pecan pesto** when pine nuts are pricey.
- Crust salmon or tofu with crushed pecans + smoked paprika.
- Sprinkle candied pecan shards over oatmeal or roasted squash.
Buying & Storage
- Pick **unblemished halves**; darker speckles = age.
- Refrigerate up to **9 months** or freeze 2 years in airtight bags.
- If they smell paint-like, they’re rancid—compost, don’t eat.
