Red Chile-Cumin Vinaigrette

In a small skillet, toast the cumin seeds over moderately low heat, stirring, until fragrant, about 2 minutes. Transfer to a plate to cool, then grind to a powder in a mortar or spice grinder.

In a mini processor, blend the cumin, chiles, cilantro, jalapeño, shallot, garlic and rice vinegar. With the machine on, add the oil until the vinaigrette is emulsified. Season with salt and pepper.
