Thanks to Buffy from Be Good Organics for supplying an easy recipe for a healthy alternative to butter! I made doubled her amount and it filled this small jar perfectly (prob around 350ml). I've halved the salt content in my recipe as I thought it was a bit too salty.
Our 2.9-year-old loves butter (even after I hide it she will pull up a stool, find it on the bench and get her fingers in!) so this will be a great alternative for her.

I'm using organic, cold-pressed ingredients:

2/3 c coconut oil
1/2 c olive oil
1/4 tsp turmeric
1/2 tsp sea salt

Melt or soften coconut oil slightly in a bowl so it becomes viscous. Add rest of ingredients and whisk vigorously with a fork until any lumps gone and consistency is smooth. Pour into a glass jar and seal and put in the fridge to set.
Stores for up to 2 months in the fridge.
