It’s a tallow based soap. Tallow fat, in the hands of a skilled soap making artisan makes for a beautiful cushion-y lather that offers excellent protection from the razor blade. Mudder Focker is a soft Italian style soap that is intended to be used with a traditional shaving brush. Simply swirl a damp shaving brush on top of the soap for 30-40 seconds and the brush will be sufficiently loaded, then you can finish creating the lather in a shaving mug or bowl. This soap is a tad thirsty so add more water to the lather if needed. If the lather is lacking slickness, that probably means it’s too dry. Make sure to let the soap fully dry after using it. This means leaving it uncovered for at least 24 hours. If you cover the soap while it’s still wet you can ruin it. If you use the soap 3-4 times a week or more, there is no reason to replace the cover once you first open it.
