What are groundnuts?
Groundnuts are peanuts. In many places, especially across parts of Africa and Asia, “groundnut” is the everyday word for peanut.
Do I need raw green peanuts for boiled groundnuts?
You will get the best results with raw green peanuts (fresh, high moisture). They cook faster and turn properly creamy. Raw dried peanuts also work, but they take longer and need more water as they simmer.
Where do I find raw green peanuts?
If you live in the South, you will often spot them in late summer and early fall at farmers markets and some grocery stores. Elsewhere, check international markets. Frozen green peanuts are also a great option and cook similarly to fresh. Thaw in the fridge first, then rinse and cook as usual.
How salty should the water be?
For a classic boiled-groundnut vibe, the water should taste noticeably salty, like a strong soup broth. If you are salt-sensitive, start lighter. You can always simmer longer in slightly salty water, but you cannot un-salt a peanut once it is in there living its best life.
How do I know when they’re done?
Fish one out, cool it for a minute, crack it open, and taste. The inside should be tender all the way through. If it is chalky or crunchy in the center, keep simmering.
Why are my boiled groundnuts still hard?
Most common reasons: your peanuts were dried (not green), the simmer was too gentle, or you did not cook long enough. Keep them at a steady simmer and add hot water as needed so they stay submerged.
Can I make boiled groundnuts in a slow cooker?
Yes. Add rinsed peanuts, water, and salt (plus aromatics) to the slow cooker. Cook on HIGH for 4 to 6 hours or LOW for 8 to 10 hours, stirring once or twice if you can. Start tasting at the early end, then keep going until they hit your perfect creamy level. Let them rest in the brine for 30 to 60 minutes when done.
Can I make boiled groundnuts in a pressure cooker?
Yes, and it is fast. Add peanuts, salted water, and aromatics, keeping the pot no more than about two-thirds full. Cook on High Pressure for 35 to 45 minutes for green peanuts (or 60 to 75 minutes for dried), then do a 15 minute natural release. Taste and, if needed, pressure cook 5 to 10 minutes more. Pressure cooking is efficient, but the texture can go from perfect to too-soft quickly, so check and adjust in shorter bursts.
Allergy note
Peanuts are a major allergen. If you are serving a group, label them clearly and avoid cross-contact with other foods.
