Custard
The great British pouring sauce and dessert base — custard ranges from thin, pourable sauce through thick pastry cream to firm set dessert; in Britain, "custard" usually means the warm, pourable vanilla sauce poured generously over pies, crumbles, and puddings; made either from eggs and cream (real custard) or from custard powder and milk (the British standby invented by Alfred Bird in 1837 for his egg-allergic wife).
