Prepare the heads of garlic by slicing off the top quarter-inch of the bulb, exposing the top of the cloves.
Put into a small oven safe dish and drizzle the top with olive oil, just enough to cover the top. Sprinkle with a bit of salt and then wrap the top of the dish with aluminum foil.
Bake for 45-60 minutes depending on the size of your head of garlic. The cloves are done when the tops start to turn brown and pushing the head gently has the cloves easily pop out of the surrounding garlic skin.
Add to your recipe or simply combine with some butter for bread or dinner rolls.
In the Pressure Cooker
Prepare the heads of garlic by slicing off the top quarter-inch, just as you would if you were cooking them in the oven. Add one cup of water to the bottom of your pressure cooker and insert a steamer basket or metal grid to keep the garlic out of the water and place the garlic on top (no need to wrap).
Drizzle the top with olive oil and sprinkle with some salt.
Cook at high pressure for 10 minutes. Once the pressure releases, transfer the garlic to a cookie sheet or oven safe dish and drizzle the top with more olive oil.
Broil the garlic head for five minutes until the cloves start to turn brown and caramelize.
