Storing bread is very important especially when it comes to homemade bread. Because they don't contain any preservatives, homemade bread can go bad easily if you don't store it properly. You can use a plastic bag to store simits. Place the leftover simits in a plastic bag and tie a knot to make sure it's not in contact with air. You can also wrap them in a cloth and place them in a bread box. Simit usually lasts for about 2-3 days, however I prefer to have it fresh. You can also reheat leftover simit in the oven right before serving.
