The Yucatan-Style Slow-Roasted Pork calls for chopping the annatto seeds along with other ingredients until a paste forms. The only annatto seeds I've ever been able to find are little pellets, hard as rocks. I've always used them to infuse oil. A few years ago, I burned up my Cuisinart mini-chopper trying to chop some. Are there other annatto seeds out there I'm not aware of?
