Every time I have potatoes in the house, I end up making this. Garlic+lemon+chilli = heaven on a plate! It's also a great way to use leftover baked potatoes. Some notes:
• You can fry the diced potatoes instead of baking them. I just avoid frying, myself.
• Hot pepper paste is perfect for this, but you can get quite close to it by using dried chilli flakes (or even cayenne powder) and tomato paste.
• Feel very free with the quantities! Have as much garlic, lemon and chilli as you like. And don't worry if you don't have cilantro/coriander leaves at hand, either, I do without it most of the time.
