No. 108 Purée d’Oseille.
Put into a stewpan four good handfuls of sorrel (after being well washed,) with a small piece of butter, put on the cover and set it over a moderate fire without water, until melted; then put it on a sieve, and rub it all through; put half a tablespoonful of very fine chopped onions, and two ounces of butter into a stewpan, pass them over a quick fire two or three minutes, add a tablespoonful of flour, mix well together, add the sorrel and ten tablespoonfuls of broth (No. 133), half a teaspoonful of sugar, a little salt and white pepper; let it boil fifteen minutes, stir in two yolks of eggs quickly, and it is ready to serve. Demi-glace (No. 9) is very good instead of broth.
