There is a bug where there are multiple recipes to choose from:
For instance Barley from Biomes'O'Plenty in any two squares of a crafting grid makes one Barley Flour, but, it also makes 2 Pam's Harvestcraft Barley which cannot be turned into flour. Shift-clicking these recipes isn't possible to create the entire stack at once, and I have run into issues making the barley flour one at a time manually where the recipe will change over to 2x Pam's Harvestcraft Barley which is useless for turning into Barley Flour to make bread as it can't make barley flour.
I don't know what mod makes the multiple recipes possible, but it is getting in the way of early-game exploration for me and forcing me to undo mistakes with cheat mode whilst learning how to make the Barley into Barley Flour, I would much prefer one Barley Flour recipe than be able to make Pam's Harvestcraft Barley out of it which can be easily found by finding it's garden it spawns from or by using the Pam's Harvestcraft market. Since Pam's Harvestcraft crops grow fairly easily, it should not be necessary to oredict Biomes'O'Plenty barley over to Pam's Harvestcraft Barley.
Also, it might mean 2x Barley Flour, but consider making the Barley grindable in an AE2 Grindstone, this would be easier overall, I pretty much don't care at all about food early-game, only that the means to acquire it is relatively easy.
