Hey Deborah! Welcome to my world!
I have given up on a lot of the grain soaking. In fact, we just about quit eating grains all together. I did make the oatmeal once with the lemon juice, and yes, if you use a fresh lemon it won't be so tart. That bottled stuff is concentrated. I tried "helping" it by adding in some coconut milk. I couldn't get it satisfactory. But I was used to making my oatmeal with milk, honey, and cinnamon and nuts. It was a hard switch!
As for using lemon juice in place of whey for other recipes, I honestly don't know if it works "across the board." Sometimes she has it in there for a substitution, and sometimes not. That's whay I go by. I *think* that if you are going to do a fruit ferment, that you must use whey. Someone correct me if I'm wrong here...
Unfortunately, I don't have a lot of answers for you. I, like you, had so many questions. I basically avoid something if I don't know the answer. What I did do was add to my book collection. I have Wild Fermentation
, which explains how to do ferments without whey. It also explains about the salt issue, which is great because if you just substitute extra salt in place of whey, the result is too salty to be edible. I also have Garden of Eating
, which is a NT style cookbook, but it's grain and diary free. That book does make use of egg powder, which is not a NT principle. There are lots of good recipes in there!
So basically, we use NT principles in food prep, but I rarely consult her recipes anymore. I use bone broths as the base for homemade soups of my own making. And because we are so limited on foods, we do a lot of "basic" eating. Our foods we do eat go something like this: roast chicken, leftover chicken in a veggie stir-fry, crock roast w/ veggies, hamburger patties, lots of veggie stir-fries, fruits, sauerkraut, seed crackers, fruit leathers, fruit smoothies, salads, fresh fruits, sprouted beans cooked in bone broth, etc. We drink water and kefir made with water kefir grains. We use all organic fruits, veggies, and even spices. And all the meats are organic, pasture-fed.
hth a bit!
