HARD SOAP Line a box with greased paper. Put the fat on the back of the range until it is melted. Mix the potash and cold water, add the ammonia, borax, and dissolved soda mix- ture. Stir it occasionally with a stick until the potash is dissolved, then let it stand until it is cold. When the fat is melted and warm (not hot), pour it into the potash slowly, stirring it all the time, and continue to stir it, from ten to fifteen minutes, until the soap is the con- sistency of thick cream. Pour it into the paper-lined box. Let it stand a few hours, and then cut it into pieces convenient for use. Do not remove it from the box for three days. Temperature of Fat Tested. — Frying fat can become very much hotter than boiling water. So we say smoking fat and not boiling fat. Care must be used to see that the fat is not too hot. The following are tests : — 1. When fat is smoking, drop an inch cube of bread into the fat ; if it turns golden brown in sixty seconds, fat is hot enough for uncooked mixtures such as doughnuts, fritters, etc. RECIPE 167. 6 lb. of clarified and strained fat 1 lb. can potash 1 qt. cold water 2 tbs. powdered bo- rax J c. ammonia dis- 2 tbs. sugar
