I’m really pleased to introduce you to Jan Berry, who is not only the author of 101 Easy Homemade Products for Your Skin, Health & Home but is coming out with her second book on August 8th. Simple & Natural Soap Making is currently available for pre-order and it will hit the book shelves after that. I’ve had a sneak peek and have only positive things to say — it’s truly a useful and beautiful guide.

Jan’s been kind enough to share a recipe from her new book so read on to learn how to make her Elderflower & Lavender soap.

Elderflower & Lavender Soap Recipe

Makes 7 to 8 bars (2.5 lbs/1.13 kg)

This natural soap recipe features elderflowers, an old-fashioned home remedy for softer skin, along with lavender essential oil for a relaxing scent.

Before you make this recipe, you’ll first need to make elderflower tea. To do so, place about ½ cup fresh elderflowers (or 2 tbsp dried) in a heat-proof cup or container. Cover with 9.5 oz (269 g) simmering hot water. Let steep for around 30 minutes, strain and cool completely. Weigh out 9 oz (255 g) for the recipe, adding extra distilled water if needed to ensure the correct weight.

Lye Solution
3.95 oz (112 g) Sodium hydroxide (also called Lye or Caustic Soda)
9 oz (255 g) Cooled Elderflower Tea, in a heat-proof jug

Solid Oils
8 oz (227 g) Coconut Oil
3.5 oz (99 g) Refined Cocoa Butter

Liquid Oils
10.5 oz (298 g) Olive oil
4.5 oz (128 g) Sunflower Oil
1.5 oz (43 g) Castor oil

Add at Trace
22 g Lavender Essential Oil
10 g Bergamot Essential Oil (optional)
4 g Rosemary Essential Oil (optional)

Equipment
Silicone Loaf Mold
Digital Thermometer
Digital Kitchen Scale
Stick (Immersion) Blender

Notes & Substitution Ideas

• Cocoa butter helps add hardness to palm-free soap recipes like this one; if you don’t have any, try using kokum butter, tallow or lard for a similar effect. Shea butter could also work well.
• If you wish to replace the sunflower oil, try using sweet almond or rice bran oil instead.
• If you don’t have bergamot and rosemary essential oil to create the suggested scent blend, try using 35 grams of lavender essential oil instead.

Step 1: Make the Lye Solution

Wearing protective gloves and eye-wear, carefully stir the lye (sodium hydroxide) into the cool elderflower tea until dissolved. Work in an area with good ventilation and be careful not to breathe in the fumes. Set the lye solution aside to cool for about 30 or 40 minutes or until the temperature drops to around 100 to 110°F (38 to 43°C).

Step 2: Prepare the Oils

Gently heat the coconut oil and cocoa butter on low heat until melted. When the solid oils are melted, take the pan off the heat and pour in the liquid oils. This helps cool down the melted oils, while warming up the room temperature oils.

Step 3: Mixing

Pour the cooled lye solution into the warmed oils. Using a combination of hand stirring and an immersion blender (stick blender), stir the soap batter until it thickens and reaches trace.

Step 4: Add the Essential Oil

When the soap batter has thickened to the consistency of warm custard, stir in the essential oil(s) for scent.

Step 5: Pour in Mold

Pour the soap batter into your soap mold. Cover lightly with wax or freezer paper, then a towel or light blanket. Peek at the soap every so often; if it starts developing a crack, uncover and move to a cooler location.

Step 6: Cut & Cure

Keep the soap in the mold for 1 to 2 days, or until it’s easy to remove, then slice it into bars when it’s firm enough not to stick to your cutting tool. Cure on coated cooling racks or sheets of wax paper for about 4 weeks before using. The soap is safe to touch 48 hours after making it but it needs the extra time to allow the excess moisture to evaporate out. For full instructions on how to cure handmade soap head over here
