Ocado British Growing Basil. Basil is one of the most popular Mediterranean herbs with its lush green leaves and pungent flavour reminiscent of Italian cooking. It's a fragrant herb that adds a burst of flavour to many dishes, simply wash the leaves and sprinkle into pasta sauces, soups, salads, and marinades. You can also use it to make fresh pesto or garnish your favourite pizza. For a refreshing summer drink, add a few leaves to a jug of water with sliced lemon and cucumber. Or, try infusing olive oil with basil for a delicious salad dressing or dipping sauce. Top Tip! The best way to look after basil is to let the plant tell you it needs watering, as it will start to wilt. The plants will quickly spring back up and the stress will actually increase the oil content they are producing, improving the flavour. It is also important not to water the plants too soon before harvesting the leaves, as this will dilute the flavour. Basil is highly susceptible to chill (below 10°C) or cold draughts and the leaves will start to blacken. Looking for more herby inspiration?
