Opperdoezer Ronde is a variety of yellow or white-fleshed potatoes. Even though it is not the prettiest looking potato, considering its irregular, oval shape, it is full of vitamins (B1, B2, B6, B11, C) and is valued by many chefs who prepare it boiled or fried, although the traditional way is to serve them boiled with creamery butter. The first potatoes are harvested at the beginning of May, and until the beginning of September, all the potatoes are harvested and then sold at auctions.
Since this variety has a very delicate and thin skin, it is mainly harvested by hand in order to protect it. The potatoes are sorted into groups - above or below 35 millimeters. One can obtain the potatoes only in the summer and autumn, making it a valuable rarity in the potato world. The potatoes are cultivated on light sandy clay soil, with a particular composition of sulfur, around the village of Opperdoes in the Netherlands region of Noord-Holland, which is why they have such a distinctively rich and creamy taste, and a distinctively low starch content.
