Further evidence that foraged foods are hot is the recent release of the Wild Vegan Cookbook by Steve Brill. I had my doubts about this book when the review copy showed up, since it just sounded a little too trendy to be good, but I've been won over. While it's definitely not an identification book (and is geared towards advanced foragers) it's fun to look through all the ideas for cooking wild plants. It's organized by season, and there is a bit of background info about each plant. There are recipes that utilize more common foraged foods such as ramp pesto and polenta with oyster mushrooms and fiddlehead ferns, but also tons of ideas for lesser-known plants, such as wisteria flower pancakes.
When it comes to the cattail, Brill says it's "the very best of edible wild plants," and explains how to prep it by peeling away the outer leaves of the shoot and using only the core, echoing BostonZest's take on the flavor resembling cucumber or zucchini. Here's one of Brill's recipes for using the plant, that riffs on the cucumber flavor and crunch—but we have to echo BostonZest's feelings about acquiring the cattails: only get foraged foods from a trusted source.
