❓ FAQ
You can use any type of lentils, such as green, brown, or bengal gram lentil (yellow split peas) for chana dal, but it is best to soak them overnight first to remove toxic lectins.
I don't need to do this however with red lentils, which also cook faster and softer than other lentils.
The spiciness of this curry depends on the type and amount of curry paste you use. You can adjust the heat level by adding more or less curry paste, or by adding some coconut milk or yogurt to the curry to balance the heat.
Yes, this recipe works on a hob or stove top. You can saute the onions first for 2-3 minutes if you wish. Then add everything to the pot and simmer while covered over medium-high heat for 25-30 minutes.
I recommend stirring occasionally, but if you find it catches, add a splash of more water and lower to medium heat, and continue until the lentils are tender.
