Garlic olive oil
An absolute staple of any cook's kitchen should be garlic oil.
A splash into the wok makes garlic prawns simple. A dribble on beef carpaccio brings it to life. Mixed 50:50 with white or dark balsamic and you have the all-purpose salad dressing that almost guarantees a cleared plate.
Garlic can be tricky stuff to work with when producing a flavoured oil - there are a number of things that can go badly wrong so this is one oil we don't suggest people try to make at home - leave it to the experts.
