Overview
Tiger nuts (also called chufa or earth almonds) are small root vegetable tubers, not actually nuts. They've been consumed for thousands of years, particularly in Africa and Spain where they're used to make horchata de chufa. Rich in fiber, resistant starch, and naturally sweet, tiger nuts are gaining popularity as a nutrient-dense, allergen-friendly snack and ingredient.

Key nutrition highlights
- Resistant starch: prebiotic fiber that supports gut health and digestive wellness
- Fiber-rich: approximately 10g fiber per ounce, excellent for digestive regularity
- Healthy fats: predominantly monounsaturated fats (oleic acid)
- Minerals: good source of iron, magnesium, potassium, and phosphorus
- Vitamin E: antioxidant support from natural vitamin E content
- Allergen-friendly: nut-free, gluten-free, grain-free option
Tip: Start with small amounts—high fiber content may cause digestive adjustment for some people.
Typical origins & sourcing
Tiger nuts are primarily cultivated in West Africa (especially Nigeria and Ghana) and Spain (Valencia region). Key sourcing considerations:
- Spanish vs African: Valencia, Spain produces premium organic tiger nuts; African varieties are traditional and often more affordable
- Forms: whole raw, peeled, roasted, or as flour—each has different preparation needs
- Organic certification: prioritize organic to avoid pesticide residues
- Processing: look for minimal processing, no preservatives or additives
- Freshness: check production dates—older tiger nuts can become very hard
Quality checklist:
- ✓ Organic certification when possible
- ✓ Origin clearly stated (Spain or specific African region)
- ✓ No mold, off-odors, or discoloration
- ✓ Stored in cool, dry conditions
- ✓ Peeled varieties easier to digest and use
- ✓ Check for added oils or sugars in roasted varieties
Preparation tip: Soak raw tiger nuts in water for 12-24 hours to soften before eating or blending. Change water periodically.

FAQ
Are tiger nuts actually nuts?
No, despite the name, tiger nuts are small tubers (root vegetables) from the Cyperus esculentus plant. They're safe for people with tree nut allergies but should be verified with your healthcare provider if you have severe allergies.
Why are they called tiger nuts?
The name likely comes from the striped, tiger-like pattern on the tuber skin, or possibly from their historical cultivation along the Tigris River region.
Do I need to soak tiger nuts before eating?
For raw tiger nuts, soaking is highly recommended to soften them and improve digestibility. Roasted or pre-prepared tiger nuts don't require soaking. Peeled varieties soak faster than unpeeled.
Can tiger nuts cause digestive issues?
The high fiber and resistant starch content can cause gas, bloating, or digestive discomfort if introduced too quickly. Start with small amounts (1-2 tablespoons) and increase gradually as your system adjusts.
How is tiger nut flour different from almond flour?
Tiger nut flour is naturally sweeter, has significantly more fiber, and is nut-free. It absorbs more liquid in baking, so recipes typically require more moisture or binding agents. It's excellent for paleo and AIP diets.
