*All* varieties of mushrooms should be cooked before eating them. Yes, this does include button mushrooms, the ones commonly found raw on salads.
According to Dr. Weil:
Mushrooms have very tough cell walls and are essentially indigestible if you don't cook them. Thoroughly heating them releases the nutrients they contain, including protein, B vitamins, and minerals, as well as a wide range of novel compounds not found in other foods...
But there are other reasons to cook your mushrooms. Raw mushrooms contain small amounts of toxins, including some compounds that are considered carcinogens. These are destroyed by cooking them thoroughly. Broiling or grilling is best.
And Dr. Fuhrman:
Avoid Uncooked Mushrooms
It's important to remember that mushrooms should only be eaten cooked. Several raw culinary mushrooms contain a potentially carcinogenic substance called agaritine, and cooking mushrooms significantly reduces their agaritine content.
You do not need to pre cook them, just slice them and scatter the raw mushroom over the pizza, the mushroom will cook through whilst you pizza is cooking.

You cannot 'cook' mushrooms as such in Minecraft. You can, however, craft a mushroom stew.

You cook them like a dry saute to get their juices out, then you add butter, sherry etc to them because they act like a sponge and soak up anything you put in the pan. The leftover evaporated juices from the mushrooms are re-incorporated to make a rich mushroom sauce.
There is no issue with garlic mushrooms in regard to the laws of kashrut unless you were to cook them with butter then serve them with meat. If a religiously observant Jew weren't to eat kosher garlic mushrooms, most likely, they just don't like them.
