Pour water into the pot of a double boiler. (see note below if you don't have a double boiler) and heat at medium/medium-high.
Place the bowl from your double-boiler on a scale and set the scale to zero/tare.
Add 19 g cocoa butter
Add 19 g beeswax, total grams should be 38 g
Put double boiler bowl into pot, over the simmering water. The cocoa butter and beeswax should melt in about 5 minutes.
Turn the stove off and add 22 g of grapeseed oil and squeeze 2 vitamin E capsules into the melted oil. Stir to combine. Add 20 drops of essential oils to your melted oil. You can use 20 of one oil or mix them up. Twenty drops is what I like, but feel free to add more or less to suit you.
Stir well and then remove from the heat. Wipe the bottom of the pan to remove any moisture. I set the bowl on a folded dishtowel to make sure it is dry. You don't want any drops of water in your balm, it will leave a hole.
Using a potholder, pour the melted oils into your metal container. I put my container on a trivet on my counters just to protect my counters.
Let the balm sit undisturbed for about 20-30 minutes until solid. Screw the lid on and apply a label!
Notes
No Double Boiler? All you need is a pot and a heat-proof bowl. Technically, I don't have a double boiler either, but I do have a metal bowl that fits well with a pot. Your bowl should rest on top of the pot and not fall in, so it should be bigger than the pot.In the perfect world, select a wide pot because it has more surface area which will ensure even melting. For a softer balm, you could substitute mango or shea butter for cocoa butter.
