Lentils soup au maigre :—Pick carefully a pint measure of
lentils, wash them well, and put them into a stew-pan with
three pints of cold water, a quarter of an ounce of salt, one
three-ounce onion, and a bacon bone if possible. Boil; then
allow to simmer till the lentils are cooked. This you ascertain
by pressing the grain between the finger and thumb. To
accelerate the cooking pour into the pan, every half-hour,
a quarter of a tumbler of cold water, starting the boiling
again after each interruption. This operation renders the
soaking of dried pulse before cooking unnecessary, and though
it adds a little to the consumption of fuel, the advantage
gained is considerable. The lentils being nice and soft, drain
them off, reserving the broth : pass the grains through the wire
sieve, with the onion, catching the purée in a soup-plate. Now
put half an ounce of butter with half an ounce of flour at the
bottom of the cleaned stew-pan, mix these over the fire till
velvety; then gradually add purée and broth together, until a
soup of the desired quantity and consistency has been obtained.
