The potato cake recipe is a perfect way to avoid food waste. You can do it if you have leftover mashed potatoes or other ingredients in small quantities in the fridge. In this recipe, I am using einkorn flour, porcini mushrooms and chestnuts, but you can replace them with other types of flour, mushrooms, nuts and vegetables.
I prepared the yoghurt at home, according to this recipe. However, you can replace it with a commercial vegan yoghurt, to shorten the time spent in the kitchen. I also tried buying chestnuts in bulk, roasting them and peeling them. I regretted it bitterly, as they were mostly rotten and I wasted about 3 hours in the process. If you do not have the guarantee that they are fresh, I recommend you buy jared ready-peeled roasted chestnuts from supermarkets.
