Spearmint is one of my favorite herbs. I always have a patch growing just outside my kitchen window. It is a fast spreading herb and needs to be thinned frequently. Fortunately I love it so its not a problem!
Spearmint is part of a larger family that includes basil and oregano.
I often substitute spearmint in recipes for peppermint since peppermint has a stronger, distinct flavor.
Candied spearmint leaves add tasty decorations to cakes and drinks. Leaves are easy to candy by painting them with egg whites and covering in super fine sugar.
Mint also works well in Middle Eastern dishes and curries. Mint is often used to tame the flavors.
