Add almonds, cashew nuts, black peppercorns, green cardamoms, white poppy seeds, fennel seeds, melon seeds, saffron strands and dried rose petals to the medium jar of a grinder or food processor and grind to make a smooth powder.

Do not over-grind otherwise, the nuts will release their oil and the powder will become sticky. Just pulse a few times. Then let the mixture cool down for 5 minutes. Pulse again and keep cooling the mixture in between. Pulse until a powder is made.

Store the powder in an airtight container at room temperature for up to a week.
