Step 2: Roast the Garlic

1. Preheat your broiler and place the oven rack just below center.
2. Wrap the remaining garlic cloves in foil with olive oil, salt, and pepper.

4. Mince into a garlic mash and set aside.

And for Step 3: Mash & Mix

2. Seal the lid, set to Manual / High Pressure for 10 minutes.
