What is Basil?
Basil is a culinary herb that belongs to the mint (Lamiaceae) family. It is believed there are as many as 150 cultivars of basil, but true basils belong to the genus Ocimum. Most culinary basils are a cultivar of sweet basil (O. basilicum) and are used in cuisines throughout the world.
Basil is a tender plant that can be grown as a short-lived perennial in tropical and Mediterranean climates, but is most commonly grown as an annual. It is native to tropical and subtropical regions of India, Africa, and Southeast Asia; however, it is now cultivated globally.
Some varieties of basil have been cultivated for thousands of years. Since basil cross pollinates quite easily, a wide variety of hybrids have emerged with flavors ranging from bold and spicy to mild and sweet. This range of flavors has made basil an indispensable herb in many kitchens world-wide and a majority of global cuisines.
This variety of flavor profiles allows dishes to maintain their traditional taste or give a unique signature to any dish by substituting a different kind of basil. Basil is also a relatively easy herb to grow in a container or as part of a summer garden, which makes it easy to have a selection of basil plants available for any type of food being prepared. And what could be better than freshly harvested basil for that special recipe?

Genovese basil, like other basils, likes rich, fertile soil, plenty of sunlight, and constant moisture to its roots. Be sure your garden soil is well amended or use good, quality potting soil for containers. Genovese basil is perfect for containers, but heavy use of fertilizers can affect the flavor, scent, and potency of the plant.
Genovese basil will form full, bushy plants if pinched back often. This frequent pinching back keeps the plant from forming flower spikes and will keep it producing those beautiful, tasty leaves. Once it begins to produce flower spikes it will then put all its energy into flower production for seeds and not continue growing leaves.
If your plant does begin to form flower spikes it’s not the end of the world – at least your basil world! The flower spikes can also be used as you would the leaves. Use the flowering portion of the plant sparingly though since the flower spikes have a much more concentrated flavor.
Mature plants reach a height of about 18-24 inches and a width of about 10-14 inches.

Storing Fresh Basil
Regular pinching back of basil plants to encourage branching and to prevent flowering can leave you with an over-abundance of a good thing! And who wants to let all that wonderfulness go to waste? The good news is that it’s not difficult to keep all that basil for use throughout the year.
Short-Term
Fresh basil can last up to about 10 days when stored properly. Just be sure the basil is dry before storing and DO NOT wash before storing. The leaves will turn dark if there is any moisture present. Don’t store in plastic wrap for this reason.
The best way to store fresh basil is to put the harvested stems in a vase of water as you would cut flowers and keep on the kitchen counter out of direct sunlight. Change the water every few days.
If you want to store your basil in the refrigerator, store it as you would salad greens. Using a salad spinner to dry the leaves is a good option and they can be stored in the spinner bowl. They can also be placed in a container loosely packed in layers. An herb keeper is another good option.
Freezing
The first, obvious choice is to make up some batches of your favorite pestos for freezing. Nothing says summer like a dollop of pesto in some soup or stew on a cold, dreary day. Filling some mini ice trays with your freshly made pestos, freezing them, and then removing to a freezer bag gets your pestos ready to go for your winter bite of summer sunshine!
Basil leaves can be frozen so they can be used in recipes as well. Blanch the leaves for a couple seconds in boiling water, then drain and rinse in cold water. Gently dry the leaves and place in layers separated with plastic wrap into a freezer container. Use your frozen leaves as you would when fresh. The frozen leaves have a more concentrated flavor so reduce the amount slightly from the amount you would use when fresh.
Another method of freezing basil leaves is to place them in a freezer bag without blanching. The frozen leaves will be quite brittle and can be crushed individually or in the bag. Be sure the leaves are dry or they will freeze together. If you are worried about them freezing together they can be frozen individually on a cookie sheet and then placed in a freezer container
Drying
Drying your basil is an obvious choice and probably the most popular method. Originally, basil was gathered into small bundles and hung upside down to dry. This is plainly inefficient since most of us no longer have root cellars or want to look like the local town witch doctor with herbs hanging from the ceiling in our kitchens. Fortunately, there are several more efficient options.
An easy and efficient way of drying your basil is using a dehydrator, warm oven, or microwave. Laying your basil leaves out on an herb drying rack is a little less efficient for space and time, but still effective.
Once the leaves are dried, crush or grind them using a mini food processor or an herb grinder. When the leaves are at the desired consistency they are ready to be placed into a spice jar.
Dried leaves can have much more concentrated flavor since there is no moisture to dilute the flavor so use sparingly. With that said, dried basil tends to lose its flavor more quickly than frozen basil but still provides a heavenly aroma and flavor to your culinary creations.
Basil is so versatile for cooking it is a natural choice for the herb garden. Thanks to how easy it is to grow and the selection available in garden centers and online, you can have your choice of varieties that will pair well with whatever dish you are preparing. Keeping your basil plants pinched back for healthy growth only makes it easier to enjoy your harvests throughout the year when you preserve them.
