First of all, let me say I have no complaints about this product whatsoever.  I bought it to use in a pecan pie recipe.  My mistake (and I'm only mentioning this, because this was my first time using agar, and I learned a lot) was in assuming that agar powder and agar flakes could be used interchangeably in the recipe (which called for flakes).  My pecan pie slices came out like bricks - haha!  So, I plan to make the recipe again, but probably with only half the amount in powder, in the hopes that my second attempt will be much more successful than the first!  The seller and product were both great!  Thank you.
