Dek Ngoo (Pigeon Peas with Peanut Butter)

Introduction

Dek Ngoo is a straightforward, protein-rich Kenyan dish of split pigeon peas cooked until creamy and enriched with peanut butter, finished with both table salt and rock salt for depth. The combination of the cooking liquid (which holds most of the flavor) and the peanut butter creates a naturally thick, savory soup that works as a main course or hearty side. This takes about 90 minutes total and requires only basic equipment.

Ingredients

• 1 cup of split pigeon peas
• Peanut butter
• Salt
• Magadi (rock salt)

Instructions

1. Soak split pigeon peas in 1.5 L of warm water for 1 hour. The peas should be plumped up and soft, and the skins that were on some of them should be coming off.
2. Sieve the water into a saucepan (all the flavor is in there), and put the water on the stove to start boiling.
3. Wash the peas, and remove all the skins-they will float easily because of the earlier soaking.
4. Put the peas in to the water you placed on the stove, then add salt and rock salt. Let it boil until the peas are mushy. There will be a froth foaming at the top while it boils-remove it with a ladle.
5. When the peas are mushy, add peanut butter and mix. There is a special contraption called ugwech that you can use, but you can also use a hand blender as it is easier on the muscles and quicker. The peanut butter will make the soup thick, so please add it according to taste and your desired texture.
6. If it becomes too thick you can add hot water to loosen the mixture.
7. Serve.

Variations

Lighter texture: Use less peanut butter (start with 2 tablespoons per serving) and add hot water gradually until you reach a porridge-like consistency rather than a thick paste. This shifts the dish toward a thinner soup while keeping the peanut flavor present.

Spiced version: Stir in ground cumin, cayenne pepper, or a pinch of black pepper during the final mixing stage. This adds warmth and complexity without changing the cooking method.

Vegetable addition: Dice and add tomatoes, onions, or diced carrots to the boiling peas about 15 minutes before they finish cooking. This introduces freshness and slight acidity to balance the richness of the peanut butter.

Creamier finish: Stir in a splash of coconut milk instead of extra water if the mixture becomes too thick. This adds richness and a subtle sweetness while maintaining the peanut butter base.

Chunky texture: Use natural peanut butter (peanuts and salt only) instead of smooth, or reserve some whole cooked peas before blending and fold them back in at the end. This creates pockets of whole peas within the smooth base.

Tips for Success

Don’t skip the sieve step: The water that drains from the soaked peas holds dissolved starches and flavor. Using it as your cooking liquid instead of fresh water is what gives this dish its depth.

Remove the froth: Skim the foam that rises to the top as the peas boil. This takes just a minute and produces a cleaner, less gritty final texture.

Add peanut butter gradually: Start with 2–3 tablespoons per cup of cooked peas and stir it in thoroughly before deciding if you need more. Peanut butter thickens fast, and it’s easier to add more than to thin it back out.

Taste for salt balance: The rock salt and table salt work together here, so add them in stages and taste once the peas are fully soft. Rock salt dissolves more slowly, so it may need extra time to fully distribute.

Use a hand blender for speed: If you don’t have an ugwech, a hand blender will mix the peanut butter into the peas much faster than stirring by hand and creates a smoother, more uniform texture with less physical effort.

Storage and Reheating

Store Dek Ngoo in an airtight container in the refrigerator for up to 3 days. The mixture will thicken as it cools.

FAQ

Can I use chunky peanut butter instead of smooth?

Yes. Chunky peanut butter will give the finished dish a slightly coarser texture but the same flavor. Mix it in the same way, adjusting the amount to your preferred consistency.

What if my peas don’t soften after an hour of boiling?

Older, dried peas sometimes need longer. Continue boiling and check every 10 minutes. Pigeon peas typically soften within 45–60 minutes of boiling, but very old stock may take up to 90 minutes total.

Can I make this without rock salt?

Yes. Use table salt only, but increase it slightly (rock salt is milder). Start with 1.5 teaspoons of table salt for 1 cup of dried peas and adjust to taste.

Is there a way to make this less rich?

Reduce the peanut butter to 1–2 tablespoons per serving and thin the mixture with hot water or broth. This preserves the peanut flavor while creating a brothier soup rather than a thick purée.
