I bought these ground almonds when a product recall meant I couldn't get any in my usual supermarkets. I was a bit nervous of buying them online, but they have proved to be of excellent quality and far cheaper per 100g than the smaller quantities available in the supermarkets. As another reviewer has said, they pass easily through a sieve to make macarons with no big lumps or bits of brown husk at all. There were some pieces that were a little too large for the sieve, but were still fine enough for successful macarons. I am now buying my second bag. I stored most of the pack in a large Kilner jar for freshness, which seems to work fine.
