Place the peeled garlic cloves and salt in a food processor. Process for about 1 minute until the garlic is finely chopped.
Spread on a baking sheet lined with parchment paper (important, otherwise it will stick!). Bake for about 45 minutes until dry and crumbly.
Remove from the oven. Wash out the food processor. Pour the mixture back into the clean bowl of the food processor and pulse several times until the desired consistency forms. (We kept ours a bit chunkier than normal salt.)
Store airtight container at room temperature for up to 1 year.
