Sieve the ash, so it has the consistency of sand
Stir the ash thoroughly in enough water to make it liquid. Let it stand for a few days
Once the ash has fallen to the bottom and the top is transparent filter the mass so that the ash is separated. For example, through an old sheet. You now have your lye
Boil the lye until it can carry a potato or an egg (at least 1/3 of the egg is above the lye)
Melt your lard by heating it as little as possible
Add lye in the ratio 0.4 parts lye to 1 part fat. The two liquids must have approximately the same temperature
Add seasalt and stir
Stir and heat on low heat on the mass for about 10 minutes. After this, the mass should only be kept warm, not further heated
Stir in the pan until a trace appears on the surface when you stir. If necessary, use a stick blender. It can take anywhere from ten minutes to several hours
Pour the mass into a mold and let it sit for about a day and check if it is firm enough to take out of the mold
Cut the soap into prefered size
Let the soap rest for 4-6 weeks before using it - test with pH stripe before use, and make sure it is pH 10 or less
