Last year, we put some poppy in amongst the wildflowers. Come August, I tried to make a tincture. All I ended up with was Really Nasty Tasting Vodka. Which is a crime and a disappointment on several levels. We're trying again this year.
My best guess is that I let the pods get too dry before starting the process.
One minor and related issue was that I want to reuse the lovely little bottles I put the stuff in, little brown/amber things with eyedropper screw on caps. And in my efforts to *clean* the darn things, I learned that the little eyedropper screw caps come apart, if you are firm and gentle. Three pieces; the glass dropper bit, the rubber bulb bit and the plastic screw on cap. Who knew? (well, *I* certainly didn't)
