Question: laurel

Does laurel contain toxic substances that develop after prolonged cooking ??

Answer: laurel

Dear Lino,
bay leaves contain essential oils that are not affected by cooking, in fact they are traditionally used in cooking as aromas in long cooking, as in stews; instead basil and parsley become toxic, even if the foods in which these herbs are cooked contain small amounts of leaves, and therefore their toxicity does not raise any concern. To be clear, to best use basil should be added to the sauce when it is ready, out of the fire; but even if we add 2 basil leaves to 1kg of sauce, and cook it for a long time, its toxicity is completely negligible.
