Yep, my recipe (usually makes enough for 8 servings is)
1/4 cup of almonds (peel the skin and leave to soak overnight)
1/4 cup of charmagaz (can use melon seeds from any english store really, again, soak overnight)
1.5 tablespoons of black peppercorns
1 tablespoon of khas khas (poppy seeds)
1 tablespoon of lechi (cardomon)
Process:
1, Peel and skin the almonds and soak overnight along with the charmagaz
2, Remove the lechi skins and grind along with the khas khas and pepper.
3, Once this has turned into a fine black powder, add the badam and charmagaz and start the ragra. This is usually hard work and takes over an hour even for a serving this size. A shortcut is to blend the nuts/seeds before the ragra to save time although I haven't personally ever done this.
4, Whilst doing the ragra, keep adding little bits of water when required. The nuts will soak up the water and become easier to crush.
5, When this has become a very fine paste (the consistency of degh), strain through a thin cloth into water
6, Add sweetener as required

Hope this helps!
