Description
Onions - raw or cooked. Onions are a versatile food that is widely used around the world. They can be eaten both raw and cooked and are often added to salads, sandwiches, sautéed or cooked as a vegetable, and used as a seasoning in various dishes such as soups and stews. Some onion varieties are ideal for making pickles due to their smaller and often spicier bulbs. Onion greens - raw or cooked. Certain types of onions, such as green onions, have edible leaves that can be used in salads while they are still young. These varieties have smaller bulbs and are typically eaten along with the leaves. By sowing them successively, they can be available year-round. Onion flowers - raw. These can be used as a garnish on salads. The flowers are somewhat drier and less attractive than those of other plants. Onion seeds can be sprouted and eaten and have a delightful onion aroma.
