A3+ (Super A3). A3 Plus, or Super A3 as it is sometimes known, is not an ISO 216 paper size. It has dimensions of 329mm x 483mm (13 x 19). This gives it an aspect ratio of 1:1.468 rather than the 1:root 2 aspect ratio of the ISO series paper sizes.
You may think of citrus fruits as the vitamin C powerhouses, but potatoes, including the skins, are good sources of this immunity-boosting vitamin. Potato skins also contain B vitamins, calcium and other nutrients. Potato skins are also rich in phytochemicals.
For a crispier potato skin, rub the outside of the potato with olive oil, vegetable oil, or butter over the skins. I like to roll the potatoes in coarse or sea salt after rolling in the oil and before baking. Place coarse salt onto a small plate. Roll potatoes lightly in the salt. The skin is so yummy to eat when baked!
