SOUFFLÉ AU GRUYÈRE.—This differs somewhat from the
foregoing. Put into a stew-pan four and a half ounces of flour,
two ounces of potato flour (fécule de pomme de terre), two
ounces of butter, two and a half ounces of Gruyère grated, and
the same of Parmesan, with a seasoning of black pepper and a
pinch of sugar. Moisten all this with five gills of milk, adding
it by degrees. Put the saucepan over a low fire, and keep on
stirring the mixture at a very moderate heat, till the paste
detaches itself from the sides of the pan; take the saucepan
from the fire, stirring occasionally till the contents are nearly
cold, then add the yolks of six eggs, and proceed to warm the
batter thus produced over a low fire for two minutes very
carefully. Lastly, incorporate swiftly with the mixture the
whites of five eggs beaten to a stiff froth, and two and a half
ounces of Gruyère cut into tiny pieces; pour this into a deep
round tin, and put it into the oven, which must not be too
hot. From twenty to thirty minutes will be required to bake
the soufflé.
