A really tasty weekday meal, which takes 30 or 6o minutes depending on how you would like your sweet potatoes cooked. Start by making the mash. For the longer version, halv the sweet and baking potatoes and roast them on an oven tray for 45 minutes (200 degrees centigrade). If you want to save time, just peel and chop the sweet and baking potatoes and boil for 20 minutes. In the meantime, fry the ginger, fresh and dry chilli, mustard seeds and turmeric in a bit of sunflower oil until the spices warm up and the mixture is well combined. Put to the side.
To make the batter, add the gram flour, plain flour, bicarbonate of soda and mustard seeds in a bowl. Add water until you have a smooth, thin batter. The consistency should be like double cream and quite runny.
Before you start making the dosas, you’ll need to finish the mash. Drain the potatoes, roughly mash them and add the fried spice mixture. Add the juice of one lime, spring onions and chopped coriander. Once the mash is ready you can start making the dosas. Put a non-stick frying pan over medium heat (don’t add any oil as the batter need to ‘stick’ to the pan to spread out thinly). Add a ladle of the dosa batter, lift the pan and tilt it all the way around until the batter has evenly spread out into a really thin pancake. Once there are little holes in the batter and the edges start to lift from the bottom of the pan, add a couple of spoonfuls of the mash in a row in the middle and gently roll into a pancake. Sprinkle some coconut and yoghurt on top and serve immediately.

2 baking potatoes
2 sweet potatoes

1 lime – halved and juiced
