Dek Ngoo (Pigeon Peas with Peanut Butter)

Pin it

Introduction

Dek Ngoo is a thick, savory pea soup built on two simple foundations: split pigeon peas simmered until creamy and peanut butter stirred in for body and richness. The recipe relies on soaking to soften the peas and lift their skins away, then concentrates the cooking liquid into a deeply flavored base—this is a dish that tastes fuller than its ingredient list suggests.

Recipe Details

• Prep Time: 15 minutes
• Cook Time: 75 minutes
• Total Time: 90 minutes (plus 1 hour soaking)
• Servings: 4

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

More savory depth: After blending in the peanut butter, add a pinch of black pepper or a small amount of crushed ginger. These won’t change the texture but will sharpen the flavor.

Lighter texture: Use less peanut butter than the recipe allows (start with 2 tablespoons per cup of peas instead of a full measure), then thin the finished soup with hot water until you reach a consistency between a thick soup and a thin stew.

Vegetable addition: Stir in finely diced spinach or leafy greens in the final minute of cooking; they’ll soften and add a slight bitterness that balances the peanut butter’s richness.

Creamier finish: Whisk in a splash of coconut milk or dairy milk at the very end, after the peanut butter is fully mixed, to add body without changing the peanut flavor.

Spiced version: Add a small pinch of cayenne pepper or chili powder once the peas are mushy but before the peanut butter, so the heat cooks into the base.

Tips for Success

Don’t skip the skin removal. The soaking loosens the skins, and removing them prevents a grainy texture in the finished dish. Rub the peas gently between your fingers as you rinse them to help the skins slip off faster.

Keep the soaking liquid. This water has absorbed starch and pea flavor—use it as your cooking liquid to build a more flavorful base than fresh water would provide.

Add peanut butter gradually. Start with a smaller amount than you think you’ll need, blend it in completely, then taste and add more. You can always thicken further, but you can’t thin it back down easily without watering down the flavor.

Skim the froth constantly. The foam that rises during boiling contains bitter compounds; removing it keeps the finished dish clean-tasting and prevents the soup from boiling over.

Know when it’s done. The peas should break apart with almost no pressure from a spoon. If they still feel firm or granular after 45 minutes of boiling, give them another 15 minutes rather than rushing this step.

Storage and Reheating

Store the finished soup in an airtight container in the refrigerator for up to 4 days. It will thicken considerably as it cools because of the peanut butter; this is normal.

FAQ

Can I use raw peanut butter instead of smooth? Yes, raw peanut butter works identically and may add a slightly more pronounced peanut flavor. Stir it in thoroughly to distribute it evenly throughout the soup.

How much peanut butter should I use? Start with 2 to 3 tablespoons per cup of cooked peas. Blend it in, then taste—if the soup still feels watery or lacks richness, add another tablespoon. Texture preference varies widely, so there’s no single correct amount.

What if I can’t find split pigeon peas? Yellow split peas or red lentils will work in a pinch and cook slightly faster (reduce boiling time to 45 minutes for yellow split peas, 20 minutes for red lentils). The flavor will be milder, so you may want to add a pinch of salt or a small amount of ginger to compensate.

Can I make this ahead? Yes, prepare it fully the day before and store it in the refrigerator. Reheat it gently on the stovetop, thinning with hot water as needed. The flavor actually deepens slightly after sitting overnight.
