Razor, Commis,
i think it's the best book i've come across (in terms of recipe closest to BIR). obviously i'm very fond of my KD1 book but the Kushi delivers well and truly on the base and the recipes. i'm going to purchase to read over the summer hols (i'm still trying to get going on KD2 but everytime i have base i end up using it up on BIR dishes).
ps on the base method i've tried quite a few derivatives and i don't mind phaffing if it's needed. i find all in then 2hr simmer, blend, add water 1 hr simmer does the job without phaff allowing me to make the other prep things in parallel.
