Ingredients

  • 4 lb old lard
  • 1 can lye
  • 2 1/2 qt water
  • 1/3 cup household Borax
  • 1/3 cup household ammonia
  • 2 tsp oil of sassafras

  2. Pour into a wooden container lined with cloth and allow to cool.
  3. When the soap has hardened, cut into squares.

Tips & Substitutions

When making Grandma's Lye Soap, ensure you wear gloves and goggles for safety, as lye can be caustic. If old lard is unavailable, use tallow or a combination of palm oil and coconut oil for similar results. Stir continuously to avoid burning and ensure an even consistency. If you prefer a scented soap, consider adding essential oils instead of oil of sassafras.

Serving Suggestions

This lye soap is perfect for daily use, especially for those who enjoy natural, homemade products. It pairs beautifully with homemade laundry detergent for a complete wash routine. For a unique experience, consider using the soap alongside a warm bath with Epsom salts or a refreshing Pickled Mango side dish to cleanse and rejuvenate.

Storage & Reheating

Store the soap in a cool, dry place to maintain its hardness and longevity. It's best to keep it wrapped in cloth or in a cardboard box to let it breathe. Avoid storing it in plastic, as this can lead to moisture buildup. If the soap softens, allow it to dry out before use for optimal lathering.
