Mediterranean cuisine to Catalonia and Murcia along Spain's Mediterranean coast. It comes in many versions, and may contain a mixture of chicken, pork, rabbit, or shellfish, sautéed in olive oil in a large shallow pan, with vegetables, and typically round-grain rice (often of the local "albufera", "arròs bomba", "sénia" varieties or similar) cooked to absorb the water and coloured with saffron. The dish may be varied with artichoke hearts, peas, sweet peppers, lima beans, string beans, or sausages. Anise is used around the Mediterranean to flavour spirits including French "pastis" and "absinthe"; Greek "ouzo"; Bulgarian "mastika"; Italian "sambuca"; Spanish "anísado"; Turkish "rakı";
Flavour (particle physics) the eigenvalues of the various charge operators are conserved. Absolutely conserved flavour quantum numbers are: In some theories, the individual baryon and lepton number conservation can be violated, if the difference between them () is conserved (see chiral anomaly). All other flavour quantum numbers are violated by the electroweak interactions. Strong interactions conserve all flavours. If there are two or more particles which have identical interactions, then they may be interchanged without affecting the physics. Any (complex) linear combination of these two particles give the same physics, as long as the combinations are orthogonal, or perpendicular, to each other. In
