• Roast each of the ingredients separately. I roasted the ingredients in the microwave, you can roast it in the oven or on the stove-top.

How to Roast the Spices in the Microwave

• In a Microwave safe round dish, first take the hazelnuts. Microwave high for 2 minutes. Remove the tray, stir the nuts well. Microwave high for another 2 minutes.
• Remove the tray. While the nuts are warm, use a kitchen towel and rub it vigorously, to remove the skin. Separate the skin and remove the nuts to a flat plate to cool down.
• In the same tray take pistachios, microwave power high for 2 minutes. Remove and add it to the hazelnuts tray to cool down.
• Now take coriander seeds and cumin seeds in the microwave safe dish, microwave power high for 2 minutes, remove the tray, stir them once and microwave high for another 1 minute
• Remove the roasted coriander and cumin to the nuts tray, to cool down. To the microwave safe dish, finally add sesame seeds and peppercorns.
• Microwave high for 2 minutes. Remove and add them to the nuts tray. Let all the roasted ingredients cool down well.

Let us Grind

• Take them together in a food processor and pulse few times to get a coarse mixture. 
• Take care not to grind continuously, you will end up with a paste. Pulse the processor, to get a medium-coarse spice mixture.

Store

• Store this spice-mix in a air-tight container and this can be used on variety of dishes. 
• I prefer to refrigerate as they contain nuts.

How to use

• You can sprinkle it on regular veggies, bread, soups, or can be used to make spice-oil/butter.
