Some recipes that emphasize using local ingredients sometimes call for fresh branches/leaves from pine, fir, and cedar trees. Is there an easy and safe way of getting, say, a ziploc bag full of these for, say, grilling and smoking salmon? Or to make a spruce-flavored ice cream?
Mainly I'm wary of trees in urban areas because of potential pesticides, roadside pollutants, and possibly that it's inconsiderate/not permitted. If I forage a small handful of material from a tree in Stanley park, or otherwise lower-populated but accessible area, is that reasonable? Or not?
