Fermenting a surplus of herbs can be a resourceful way to preserve them and immortalize their delicate lifespan. Simple pantry ingredients such as miso paste, garlic, apple cider vinegar and sea salt help transform the herbs into a savory jar of fermented pesto. The salt in particular reacts with the chlorophyll in the herb leaves, helping the mixture stay vibrant throughout the process.
This ferment runs its course in the refrigerator, which can be a great way to dabble in the art of fermentation without having potentially pungent-smelling jars lining your kitchen counters.
The mixture is then utilized as a pesto spread on garlic bread. Not having to wash and chop the herbs and garlic when preparing the garlic bread is a game changer when it comes to prep time. The garlic flavor finish is also a bit milder and sweeter, making the herbaceous notes of the parsley more prominent.
What鈥檚 Good to Know with Chef Olivia:
- It鈥檚 not recommended to ferment with oil or nuts because of the high fat content. This can potentially cause the jar contents to go rancid and can also possibly harbor unwanted bacteria.
- Try making fermented pesto with other fresh herbs like basil, sage or chervil.
- Massaging the herbs with sea salt helps break down the plant cells, helping kickstart the fermentation process.
- Destem parsley or any fresh herbs you are using for best results.
- Use your jar of fermented parsley garlic pesto in soups, chicken salad or even green goddess dressing.
