Oil on low heat with garlic- be careful not to burn garlic

Cut mushrooms- ideally into quarters

Throw mushrooms into pan of oil with garlic in

Stir slowly again making sure garlic not burning and checking mushrooms all fully covered in hot oil.

Cook until mushrooms drop size by a quarter ie half cook them so they don’t lose shape or flavour

Drain (but save) the oil. Stir 1 tbsp or garlic purée into cooked mushrooms and add thyme, rosemary and a small smidgen of nutmeg.
