Basil is a summer plant. When the nights get cold, basil turns unhappy. It yellows and loses flavor. Here in LA that doesn’t happen until quite late in the year. Erik just pulled out our summer basil a couple of days ago to make room for winter plants. I’m replacing it–in a culinary sense–with Italian parsley, which loves cool weather, but hates the heat. It seems our gardening year swings between the basil and parsley poles.
I made the last of our basil into basil cubes, which is my favorite way of preserving it. Just wash and coarsely chop your basil leaves and shove them into an ice cube tray, so that there’s a spoonful of basil in every cube. Cover with water and freeze. Pop them out of the trays and transfer them to a ziplock freezer bag. Throughout the winter, whenever you want a little fresh basil flavor, all you have to do is grab a few cubes. Toss the cubes straight into sauces, or let them melt to retrieve the leaves alone to use for toppings, salad &etc.
