Superfine Sugar

Also known as bar sugar or caster sugar, this white sugar has very fine granules that dissolve easily and blend thoroughly, leaving no trace of grittiness. Superfine sugar works beautifully in finely textured genoise and angel food cakes and in meringues, where it minimizes the chances of undissolved sugars “beading” or “weeping.” Superfine sugar is usually available in 1-pound boxes, but if you can’t find it, you can make your own reasonable facsimile by buzzing regular granulated sugar for a few seconds in a food processor.
