Combine the coriander seeds, cumin seeds, mustard seeds, anise seeds, fenugreek seeds, and allspice berries in a skillet. Toast over medium heat until the color of the spices slightly darkens, and the spices are very fragrant, about 10 minutes. Remove the spices from the skillet, and allow to cool to room temperature. Grind the spices with the turmeric in a spice grinder. Store in an airtight container at room temperature.
