There’s a few ingredients missing from the recipe he puts in the comments so watch the video closely if you’re going to try it.
Also 1kg of dried rice - I measured out that amount and yes, it’s the same as he uses but it’s just way too much.
Good news but it’ll be a while before I can replace the 20TB drives in my NAS with these.
