I did receive my order.
You don't need to soak sprouted flour, the sprouting has already reduced the phytates (and increased some vitamin content as well). Long, acidic soaking probably does a more thorough job of reducing phytates, but sprouting is good enough for me.
I feel fine about not grinding this grain myself, it's ground right before it's shipped (so they say, I have no way to verify that) and I store it in the freezer so it shouldn't be going rancid.
I think it says on Summer's website that their flour is drier than regular AP flour so you might need to use less, but I've found that with all spelt flour, it actually soaks up less water than standard wheat flour, so if I'm using a recipe that calls for wheat flour (either AP or whole wheat), I just pack the spelt flour down in the measuring cup rather than a scoop-and-level, non-packed measure. That usually results in an appropriate texture, whereas if I don't pack it down when measuring then the batter or dough will often seem too wet, in which case I add a little more. There are some recipes I use with weight measurements for flour instead of volume, I just use the same measurement by weight of sprouted spelt and they work out fine. You'll probably just have to experiment a little with the recipes you typically use to see how they come out, if it's a recipe you know well you'll be able to tell if the batter is too wet and needs more flour.
