Drain both vegetables thoroughly before cooking. Waterleaf naturally releases moisture, so additional stock should be used sparingly once the vegetables enter the pot.
Add the Ugu near the end of cooking to preserve its leafy texture, deep-green appearance and distinctive vegetable character.
The finished soup should be rich with vegetables and lightly coated in palm-oil broth rather than swimming in liquid.
Serve warm with eba, pounded yam, fufu, oat swallow, plantain-flour swallow or your preferred heritage accompaniment.
