In a clean, greasefree bowl, beat the egg whites slowly until frothy. Add cream of tartar and increase the speed and continue beating until soft peaks for, then stiffer peaks that flop over only slightly.

To serve, uncover the loaf pan and dip base into hot water for 10 seconds. Invert onto a board and peel off plastic wrap. Slice and serve with coffee sauce and chocolate curls.
