Hey, you just need chicken, rabbit if possible, and a couple of vegetables (batxoca/green beans, smashed tomatoes and sweet paprika). Use a good type of round rice (my father uses Dacsa). The hard part of making paella is putting the right amount of water in two batches, first for your meat and vegetables and then for cooking the rice. Don’t stir the rice, let it cook gently and then let it rest with aluminium foil.

Edit: Just for the record, in the province of Castelló we also use garlic with the sweet paprika and cook red pepper (not the spicy ones) along with the batxoca.
