Preheat the oven to 400 degrees F.

Remove the outer layers from the head of garlic so the individual cloves are exposed. Chop off the top ¼ inch of the head so you can see the raw cloves within their skins.

Place on a 9x13 sheet of foil, drizzle with olive oil, and wrap up so the packet is tightly sealed. Roast in the oven for 30 minutes, until the cloves are soft to the touch. Remove from the foil packet and allow to cool.

When cool enough to touch, squeeze the cloves out of their skins and add to a food processor. Puree the garlic clove along with the vinegar, mustard, honey, salt, and ⅓ cup olive oil. Taste and add more olive oil as necessary to reach the consistency you like. This should be a thick dressing - much like Caesar.

Store in an airtight container for up to 2 weeks.
