🥔 Kenyan Mashed Arrowroots
Nduma ya Kupondwa
Kenyan Mashed Arrowroots — nduma boiled until completely soft, then mashed with butter and milk into a smooth, mildly flavoured mash with a dense, satisfying texture. A traditional Kenyan side dish especially beloved in the highlands.
Mashed arrowroots have a distinctly different character from mashed potatoes — denser, slightly sticky, and with a subtle earthy sweetness. They are deeply comforting and pair beautifully with rich stews and grilled meats. In Central Kenya, nduma ya kupondwa is a traditional side dish that appears at both everyday meals and celebratory occasions.
Ingredients
Equipment: Large pot, Potato masher, Measuring spoons
- 600g arrowroots — peeled and cubed
- 2 tbsp butter
- ¼ cup warm milk
- 1 tsp salt
- ¼ tsp black pepper
Method
- Wear gloves to peel arrowroots — the raw sap can irritate skin. Peel and cube into even pieces.
- Boil in salted water for 30—40 minutes until completely soft throughout.
- Drain and dry over low heat for 1 minute.
- Mash with butter until smooth. Gradually add warm milk.
- Season with salt and pepper. Serve hot.
Chef Tips
- Arrowroots have a slightly sticky texture when mashed — this is normal and traditional.
- Do not over-mash or they become gluey.
- Adding a little cream cheese makes them luxuriously rich.
Common Mistakes to Avoid
- Not cooking thoroughly — undercooked arrowroots are unpleasant and difficult to mash.
- Over-mashing — creates a gluey paste.
The Science
Arrowroots contain a mucilaginous starch that becomes slightly sticky when mashed. Unlike potato starch, arrowroot starch does not become gluey when briefly overworked, but extended mashing will tighten the texture significantly.
