I buy it at
store.honeyvillegrain.com/blanchedalmondflour5lb.aspx for $30/5 lb.
They just had a sale that would've saved 10% off I think.
If you sign up on their mailing list you get coupons and sale notices and no spam.
5 lbs. last me a long long time because I don't use mine full strength, too much insoluble fiber for me. I mix half shredded veggie (squash or carrot) and half almond flour for muffins, etc. and then add other stuff like blueberries or raisins.
I'm going to make some biscotti soon because we'll be on vacation and need something that travels better than muffins.
If I could find a low cost source of blanched almonds I'd think about
making my own flour like suebear. Haven't looked into that yet.
