I don't use the base from this book any more i just use my regular base, which is JB's base, because of the Balti Powder mixes i use from the book i have not really noticed any difference in flavour and my customers haven't commented either.
I do use a slightly thicker base when making a Balti, if that makes sense, i don't water down a certain amount of base. I do make a lot of base so i can make one base thick and the other as JB states in his recipe.
