Attached is photo of the mortar that I have. The pestle is wood. I don't use it very often but have had it for probably 20 years. All the little grooves seem to catch things more than help "mush" 'em up. I had it out the other day for garlic and fennel seed and didn't feel like it did a very good job. Do any of you have one like this? What would you recommend instead of? Thanks.
