We experimented last week with vegetable papyrus. We par-boiled zucchini, yellow squash, carrots and onions for about 5 minutes, then sliced on the thinnest setting on a fancy mandolin. Then we laid the slices out onto some dirty pellons and lots of felts/towels, and pressed them in the hydraulic press, slowly adding more pressure. We exchanged the wet towels dry ones, and pressed again, about 5 times. By the end, they were super flat, and just slightly damp. We left them on to dry flat on the pelons. In a couple of days, this was the result!
The pieces are very translucent and delicate. I have a feeling they will loose their color over time, and become more brittle. But for now, how stunning!
