Preheat oven to 400 f (200 celsius)

Cut the top off of the garlic to expose the top of the cloves.

Wrap garlic in a double layer of tin foil.

Put in preheated oven for 45 minutes - 1 hour (until heads are soft and cloves are golden)

Let garlic cool enough to handle then squish cloves out into bowl.

Add olive oil and salt then mash with a fork.

Store in fridge for 1 week or freeze indefinitely.
