I think the books are likely completely different animals with similar names. The cookbook I recommend the most is Ratio by Michael Ruhlman. . Recipe’s are great but who is ever cooking exactly 2 gallons of sunchokes or 1.25 lb. Ruhlman taught me to look for the ratio in this case 5-6% salt brine. After that the exact quantity didn’t matter. If I made 1 gallon of 5% or 2 gallons brine I wouldn’t go wrong either way. I did end up with extra vinegar-sugar brine but Carrots are cheep.
