Place the almonds into a blender/food processor or seed grinder. * Depending on if you want to make just enough for a particular recipe or a large batch, it's good to note that it's usually around a 1.5:1 yield of almonds to almond meal. i.e., 1.5 cups of raw almonds will give you around 1 cup of almond meal.
Pulse the almonds for 10-15 seconds at a time. In between pulses, shake up the blender to make sure the nuts are close to the blade again and not clumping up in the jug, then pulse once more. ** The almond meal is ready when it has a fine bread-crumb like consistency.
Sieve the powder to collect larger bits and then grind them again.
Transfer into an air-tight jar/container. You can store this in the fridge for 1 month or the freezer for 3 months.
*You can also use a coffee grinder for this. However, this only allows you to make tiny portions at a time. Plus, you also run the risk of the almond meal having a slight coffee taste - if you use it for coffee too. ** You can also leave the blender running for these short bursts, if you don't have a 'pulse' feature, as such. However, do this in short bursts, with breaks in-between. Otherwise, you run the risk of over-blending your almonds and running into almond butter territory.
