I've had success by grinding the freshly cleaned & dried cilantro in the blender with just enough oil to make a paste. If I'm saving it for Mexican cooking, I use canola oil. For Thai, I use peanut oil. Drop by tablespoonsful onto a baking sheet, & freeze until solid. Remove & store in a freezer bag until needed. Doesn't have much texture when used, but retains its color & flavor. Joan Mark Barringer said, > Many of you may already know this, but I thought I would share a keeping > tip on cilantro.
