Add everything to the slow cooker and cook on high for 2-3 hours or low for 6 hours.
You can add a little oil to the pan first too if you like, as I did, but it’s not essential.
If you find it becomes too dry then you can add a little extra water.
If it’s too sloppy then adjust the slow cooker lid so it’s at a right angle and letting out some of the steam whilst on high for around 1 hour.
Serve with fresh coriander and a squeeze of lime.
For the cashews, toast lightly in a pan until they started to brown and then sprinkle on top of the dahl.
Goes well with rice or a naan bread.
