I've use this brand before and it is comparable in quality to the Organic Gemini, which not only is much more expensive but No longer is Organic according to the package label. A few months ago the Organic Gemini brand was out of stock, so I decided to try 5 or 6 different brands from Amazon to compare them, and by far the Anthony's Organic Tigernut flour was the best. It's much lighter in color, less dried out, more moist, less gritty and better texture, and also my recipes were less flat and more fluffy in texture, while most of the other brands were very dark and dried out, like old. The clumps are normal because it's made from dry tubers, by the way, since it's 100% tigernuts with no other drying ingredients. I always use a sifter anyway when making my AIP flour mixes. I've using tigernut flour successfully for baking AIP (Autoimmune Protocol) recipes for more than 4 years now, because of terrible histamine and sensitivities to all grains, dairy and eggs. So I was very happy to find a good quality price for a lower price since it's the main tuber flour that I use for baking. Tigernut flour also have less carbohydrates and a lower glycemic index than cassava flour so it is healthier for my diabetic husband.
