Freshly roasted garlic, is best enjoyed within a few hours of making it, as the cloves can dry out if refrigerated for a couple of days, though it will still be good to eat. Freezing however, is a great way to preserve it, so you can roast up a few bulbs and have them to hand. Remove the roasted cloves from the bulb and freeze them solid on a baking sheet before storing in a container or bag. They will keep well for several months and can be added frozen into recipes, or thawed in the fridge or at room temperature.
