As a service to our readers, we occasionally publish here recipes for concoctions made from snails. This one, from the 8 September 1866 issue of the British newspaper the Penny Illustrated, was said to be good for "consumption".
I endorse this recipe because it doesn't require that the snails be killed.

The previous recipe was for a snail-based cough syrup.
