Is almond flour the same as almond meal or ground almonds?
Yes. If you are unsure, check the ingredients on the package; the only ingredient listed should be almonds. If there are other ingredients, it’s not the same thing and should not be used in a recipe that calls for almond flour. Other names for almond flour are powdered almonds, almond meal, and almond powder.
(Some say that only blanched almonds are used for what is called almond flour, but I’ve seen unblanched almond “flour” listed as such, so that’s not always the case.)
What is the difference between natural and blanched almond flour?
Blanched almonds have had theirs skins removed. This is done by dropping them in boiling water for about a minute. Draining them in cold water, and slipping the skins off. Unblanched almonds have their skins on. Both kinds of almonds are then ground up for almond flour. A majority of almond flour you’ll come across is made from blanched almonds since most people prefer the lighter crumb and appearance in cakes and other baked goods. Some bakers say that unblanched almond flour can make baked goods heavier, but I’ve not found it to make a tremendous difference. So you can use either, unless one is specifically called for in a recipe.
