Cut the top off the garlic, add some olive oil and salt. Then, cover in foil and bake at 400°F for 60 minutes.
Add the butter, shallots, parsley, garlic, nutmeg, caper juice, vinegar into a food processor and process until smooth. Wait to salt until the end because the butter is salted.
Add the butter mixture onto the escargot dish, reserving a little for the top. Top this with escargot and then add the rest of the butter.
Bake at 425°F for 10-12 minutes. Then, broil for 1-2 minutes.
