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) basis to the flavor-eigenstate/mass-eigenstate basis for quarks underlies the Cabibbo–Kobayashi–Maskawa matrix (CKM matrix). This matrix is analogous to the PMNS matrix for neutrinos, and quantifies flavour changes under charged weak interactions of quarks. The CKM matrix allows for CP violation if there are at least three generations. Flavour quantum numbers are additive. Hence antiparticles have flavour equal in magnitude to the particle but opposite in sign. Hadrons inherit their flavour quantum number from their valence quarks: this is the basis of the classification in the quark model. The relations between the hypercharge, electric charge and other flavour quantum numbers hold
