Almond meal can generally be found at well-stocked markets in the Los Angeles area. But occasionally I'll hear from a reader who can't seem to find it at any local stores.
No worries. Almond meal (or flour) is nothing more than ground almonds. Simply pulse the almonds in a food processor until finely ground. Be careful not to pulse too much, however, or you'll end up with more of a spread, or almond butter. Either regular (skin on) or blanched almonds are fine.
