What you need – freshly-picked basil, olive oil, salad spinner, food processor, ice cube trays, spatula, plastic wrap or wax paper.
- Pick your basil and wash thoroughly in a sink full of cold water, swishing to rinse off all soil. Pick off the leaves.
- Dry the leaves thoroughly. A salad spinner is perfect for this.
- Place the leaves in a food processor; slowly add olive oil until a sort of paste forms, scraping the bowl when necessary.
- Quickly spoon the basil into ice cube trays. Basil exposed to the air starts to turn black pretty quickly. Cover with plastic wrap or wax paper. Freeze until firm. Remove from ice cube trays and store in freezer bags or containers.
