Excellent Yest.
Put a pint of well boiled milk into a hasty-pudding, and beat it till cold and there are few lumps remaining; then put to it two spoonfuls of yest and two of white powdered sugar, and stir it well. Put it in a large bowl not far from the fire, and next morning you will find it risen and light. Put it all to your flour, which must be mixed with as much warm milk and water as is necessary to make it into dough, and put it to rise in the common way.
