Need simple cannabutter recipe - newbie :)

Hello everyone,

So, as the title says I am looking for a simple cannabutter recipe. I wish to make it with coconut butter/oil in a slowcooker.

Since there are a lot of recipes online I got confused about following things:

Measures - I would prefer recipe in grams

Should I ad water? In some recipes water is added...

Can I cook it directly in slowcooker or should I put everything in a glass jar and then in slowcooker filled with water... Like, people do both.

I would really appreciate a recipe and advice from someone who has experience with making this.

Thank you.
