In French or Belgian cuisine, pâté may be baked in a crust as pie or loaf, in which case it is called pâté en croûte, or baked in a terrine (or other mold), in which case it is known as pâté en terrine. Traditionally, a forcemeat mixture cooked and served in a terrine is also called a terrine. The most famous pâté is probably pâté de foie gras, made from the livers of fattened geese. Foie gras entier is fattened goose liver cooked and sliced, not made into pâté. Pâté en croûte is baked with the insertion of "chimneys" on top: small tubes or funnels that allow steam to escape, thus keeping the pastry crust from turning damp or soggy. Baked pâté en croûte usually develops an air bubble under the crust top as the meat mixture shrinks during baking; this is traditionally dealt with by infusing semi-liquid aspic in the hollow space before chilling.
