Peel, and finely grate the ginger. Pick the leaves off the coriander, and finely chop the stalks.
The remaining half of the red onion should be sliced as thinly as possible, then left to soak in ice cold water.
Over a medium high heat, melt the butter, and fry off the red onion with the salt.
When the onion is translucent, add the garlic and chilli, cooking them out for about one minute.
Add all the dried spices, and toast them until fragrant.

«Paneer is a simple cottage cheese that can easily be made at home if you cannot find it in the shop. However, it can be substituted with strained cottage cheese if it is unavailable. The cashew nuts are used as a thickener, and can be omitted.»
