For this recipe, you need a juicer. I love my Hurom HU 700 slow juicer. Remove the part with ailettes (see picture below) and feed your juicer with your preferred nuts. I like raw walnuts for its big ratio of omega 3. Use the paste coming out from the left side of the juicer to refeed again until you like the consistency of your mixture. You will collect the real butter outside the grind. Use all the forms of your nuts you find in and out your machine to make a nice crunchy (or not) paste. Be careful not to overfeed your machine. Too much pressure will give you headache to open the lid without damage … Experience, yes….
Quantity: I made 272 gr of paste with 310 gr raw walnuts.
Price: It costs me 280 THB (+/- 7.5 Euros), twice less than in the supermarket here in Bangkok.
