In the process of making basil sauce, there are a lot of details need to pay attention to, otherwise the made basil sauce will be bitter.
To pick fresh young basil leaves and remove the decaying ones, you can better ensure the flavor and prolong the preservation period.
In the process of breaking it up with a masher, add ingredients such as basil leaves, pine nuts, garlic cloves, parmesan cheese, and olive oil in small batches.
It's also important to preserve it correctly. After the basil sauce is bottled, it's not sealed directly, but a layer of olive oil is poured over it to "seal" the sauce and keep it fresh, prevent it from oxidizing and darkening, and prevent it from tasting bitter.
