paradise, you mean just a stock? even just gently simmering in water will do. Bring to a gentle boil and keep it there, about one hour. Or you could use a court boullion (white wine, mire poix). You can enhance with garlic or tarragon. But the simpler the stock is, the more options you have later. Skim, skim, skim. Then ladle the stock gently through a chinois.
