Don't try to do everything at once, start small especially if like me, you are doing it the first time. Just do what's written, don't add anything, don't rush any steps. It's written in a specific way for a reason.
Or else you'll end up like me with 500mg of yield from 250g of mhrb which is like 0.2%.
So yeah just be patient and follow the steps slowly. Read it 3 times before you do something.
The one who asks never gets lost.
