Onions, white sweet, when we can get them, we mostly use them on salads and sandwiches. However, not all of this variety are sweet, which we understand has to do with the soil conditions that they are grown in. See more about them below.
About White Sweet Onions:
We purchased these three inch diameter white sweet onions at a local farm store, where they were sold freshly harvested with the green tops and roots still attached. Later in the season they continued to sell them, but without the tops and roots, just as they would look in the supermarket. These white sweet onions are mild tasting and great eaten raw in salads and sandwiches. Select white sweet onions that are firm to the touch, particularly at the stem end, which is usually where the first signs of spoilage begin. Also make sure there are no signs of mold, which is usually black. See the nutritional chart below.
